Hello ! check your eyesight))))) 120-140 l

I wrote on 1 eye, but there is also a second one! then you will get the displacement you expect

Hello, usually this is 0.7-1 liters, if you take a larger quantity, marmots or other animals may come, they say proteins are now in short supply and there is not enough for everyone. I agree completely - from the photo only by eye, with respect

Hello . If after the ride you don’t or are too lazy to wash off all possible accumulations of dirt on the body, then don’t worry too much - you’ll quickly outstrip us. and after such repairs, we are ready to lose this competition in rust to anyone and anytime, and if we don’t get any prizes in this competition, I will consider it an honor. because only an idiot can be worse than this bastard. And if they take on the car together, the car simply has no chance.

I don’t understand a damn thing about your competition there)))

You wrote about the Kruzak that in the warm weather it also began to participate in these competitions and you are trying to remove it from the race by parking it on the street. How about a nurse for a friend? Haven't you looked under the kung?

The nurse there has a different design and there is nothing there to rot. The kung itself is plastic

but still take a look. Kung himself cannot live independently. especially plastic. I could be wrong, but the kung is placed on a 712t base and there the iron bottom is the same as everyone else’s

Yes, I specifically tried to find the same places where yours is rotting there and did not find it, although I looked without a hole from the outside. It seems to me that the design is made differently there.

you have a note in your blog about BarobanoFF2013, everything is visible there. It’s precisely those same floor enhancers that have given us headaches.

Do-it-yourself gas tank repair: four proven methods

Roads are not always perfect, and it is difficult to insure against breakdowns while driving on them. The most common problem is tire breakdown, but this problem is not so difficult to fix, especially if you have a spare tire with you. Much more questions arise when you need to repair the gas tank yourself if it suddenly turns out to be broken and fuel begins to pour out of it. It is not always possible to call a tow truck, and in some situations there is no need at all, since any driver with the appropriate knowledge can repair the gas tank on the spot using available means.

Do-it-yourself gas tank for a motorcycle

I’ll separate the technology, maybe it will be useful to someone

Fiberglass tank 8 liters

1. Foam plastic blank is cut into pieces. I got 4 pieces.

Next, we glue them together with glue for ceiling tiles or any other, but only so that the foam does not corrode. Let it dry. The result is a blank for the “boob”

Drawings of templates in three projections were made in advance in Compass, printed and plywood copies were cut out from them. two plywood copies of each projection.

I covered unnecessary recesses and sinks with plasticine (thanks to my daughter)

2. Neck and tap

Next, the neck and nut of the gas valve were made. A bolt is also welded onto the nut support plate to ground the tank.

A jumper is welded between the neck and the nut

Fiberglass fabric is cut into strips 100x300 and 100x150. The glue is mixed in 150. 200 grams. Mixing the resin with the hardener and impregnating the fiberglass is best done on a sheet of glass and wearing rubber gloves. I made 6 layers of fiberglass in total. The neck of the tank with the nut for the faucet is glued in after the third layer. Waiting time between layers is 30. 60 minutes. It is advisable to glue all layers together in one day. After polymerization, etch the foam with acetone/degreaser/gasoline

After fitting and marking the tank, we glue the fastening ears made of fiberglass. Also 6 layers.

Use a petal disc to gently sand out large uneven areas.

Then we sand again and putty the imperfections left after the first layer. Let it dry and sand again.

Degrease and prime in 2 layers with intermediate drying

How to detect damage to the gas tank

Most vehicles have a fuel tank located on the bottom, which increases the risk of damage when driving over rough terrain or poor quality roads. A simple blow to the gas tank can cause a dent in it, but targeted pinpoint damage will result in a puncture. The following factors indicate that the gas tank is broken:

• The smell of gasoline began to be clearly felt inside the car;
• The fuel level needle began to approach zero faster than usual.

If you notice signs of a breakdown in the gas tank, you should stop the car and turn off the engine. After this, carefully inspect the gas tank for damage and leaks. When they are found, you will need to act, depending on the specific situation. Below we present several ways to repair a fuel tank yourself in road conditions.

All automobile gas tanks have rounded corners for one simple reason: they are welded from two halves stamped under pressure. The press will not squeeze out straight sharp corners at four points at the same time, because... the metal will tear, and this is not necessary.

DIY gas tank repair

The fuel tank is quite simple, and it is a reservoir that is filled with gasoline. In this case, the gas tank can be made of steel, aluminum, plastic or other materials. It is better to replace a broken gas tank with a new one; inexpensive options can often be found at various car “dismantling” sites. However, if you are on the road, it is possible to repair the tank yourself in order to get to a service point or continue operating the machine until you buy a new part.

Method 1: Repairing the gas tank with a rubber pad and a bolt

The most effective way to repair a gas tank on the road is to seal it with a rubber plug. It is advisable to use it when there is a breakdown in the fuel tank of a large diameter, and a bolt can be inserted into it. Repairs are carried out as follows:

1. The hole in the tank that needs to be repaired must first be expanded to the diameter of the existing bolt;
2. Next, a washer with a rubber gasket is selected for the bolt;
3. Next, you will need to install a bolt through the neck of the fuel tank into the prepared hole and place a washer and rubber gasket on it from the outside and tighten it with a nut.

Important: Select rubber as a gasket that does not dissolve under the influence of gasoline. Do not use “raw rubber”, which will quickly become unusable.

It should be noted that this method of repairing a gas tank is popular among truckers. By sealing the hole in the fuel tank in this way, you don’t have to worry about its reliability. If it is not possible to replace the gas tank in the near future, it is recommended to remove the threads and paint the joints to avoid corrosion. If the patch is done correctly, the gas tank can last for months or even years.

Method 2: Solving the problem with the gas tank on a carburetor engine

Carburetor engines are actively becoming a thing of the past, but they still remain on older car models, and it will be useful for drivers of such cars to know what to do if the gas tank breaks down. The design of the carburetor with diaphragm-type fuel pumps is such that it allows you to use any container as a gas tank by lowering the hose that comes from the gas pump into it.

How to make a fuel tank with your own hands?

The main purpose of a fuel tank is to safely store fuel. This is the longest-lived part of the car. However, she also needs periodic care and prevention. Moreover, the tank may be damaged as a result of mechanical stress. All this requires knowledge of the technology for its restoration, repair and replacement.

Gas tank restoration and repair

In modern passenger cars, the fuel tank is usually located in the rear lower part of the body. This is due to both the requirements for adjusting the center of gravity of the machine and the safety of control. However, with this arrangement, the tank body is constantly exposed to road dirt and chemicals, which in turn leads to corrosion.

Even the most modern galvanized tanks cannot resist rust for long. We can say that corrosion is the main cause of leaks in tanks.

Through the hatch, fuel enters the neck and then goes directly into the tank itself.

Safety requirements

When repairing a fuel tank, basic safety requirements must be observed:

1. It is imperative to make sure that the machine is securely fixed in one place.
2. Start work only after the tank has been completely emptied, washed and dried.
3. Decide whether it is advisable to dismantle the tank - sometimes you can carry out repair work without removing it.

It is most convenient to drain gasoline using special pumping units

Removing the fuel tank

In most cases, the gas tank must be removed for repairs. The fuel level should be minimal. For dismantling you will need:

• flat and Phillips screwdrivers;
• ratchets;
• pliers.

The dismantling itself is carried out as follows:

1. The pressure in the fuel system is relieved - the power plug is disconnected from the fuel pump. Usually the pump is located in the gas tank itself, and you can reach it through the passenger compartment by lifting the rear seat.
2. The car is driven into a viewing hole or jacked up from behind.
3. From below the tank, loosen the clamps with a screwdriver and unscrew all the hoses.
4. From the side of the rear beam, the two bolts securing the tank to the bottom of the body are unscrewed in any order. When doing this, you should hold the gas tank so that it does not fall.
5. The tank is carefully pulled out from under the car.

Basic fuel tank faults

The most common gas tank malfunctions are:

• broken hull;
• corrosion;
• depressurization of welds.

And if you take into account the condition of most Russian roads, it becomes clear why drivers so often repair or change tanks.

Natural corrosion of metal cannot be discounted. The older the car gets, the more likely it is that the tank will begin to rust intensively.

Corrosion eats away at the metal surface of the tank

Cable repair

To repair the gas tank flap cable, you can use glue, cold welding or soldering. However, this will only restore the cable for a short time.

A more reliable way to repair a cable is to use metal ties or wire. By tying a broken cable, its fibers are strengthened. After this it will last a long time.

A broken cable can be repaired in various ways

Hatch repair

The hatch is one of the most problematic elements of the fuel tank. With prolonged use, the larva responsible for opening the hatch may break or begin to jam. This problem is solved as follows:

1. The trim on the side of the tank neck in the trunk is removed.
2. The power plug is disconnected from the mechanism.
3. The bolts are unscrewed and the hatch locking mechanism is pulled out.
4. Most often, the larva jams due to the fact that the rod jams. Sometimes the stem itself may break. Therefore, you will need to either straighten the position of the rod and lubricate it, or install a new rod in the mechanism.

The same steps are performed when replacing the hatch. After dismantling the locking mechanism, the fastening bolts from the body side are unscrewed.

To repair or replace the hatch, it is necessary to remove the locking mechanism and unscrew the fastening bolts

Dent repair

Small dents on the surface of the gas tank can be corrected on your own. If the dent appears from below, then you can often do without dismantling the tank.

For repairs, you will need a compressor or a regular pump. The procedure is as follows:

1. The rear seat rises.
2. The gas tank flap opens.
3. The line connected to the fuel level sensor is removed.
4. A hose from the compressor is connected in place of this line.
5. The cavity of the tank is filled with air under a certain pressure. At this time, the assistant must close the check valve located at the neck.
6. Even with minimal pressure and proper operation of the valve mechanism, dents will be eliminated.

In this case, you should stop work exactly at the moment when the dent disappears.

Sealing seams

Often a seam on the fuel tank comes apart. This problem can be solved in different ways.

Sealing seams on your own using traditional welding is difficult for the average car owner for obvious reasons - you need a welding machine and skills to perform such work.

Therefore, recently the so-called Poxipol cold welding has gained great popularity. This is a composition that can efficiently seal seams on a metal surface.

The procedure for cold welding is as follows:

1. The workplace is cleared of dirt.
2. Gasoline is drained from the tank.
3. The seam is degreased and cleaned with sandpaper.
4. Poxipol is evenly applied to the seam and left for one hour.

Within an hour, you can fill the gas tank with fuel and continue to operate the car.

Poxipol quickly and efficiently seals seams on the fuel tank

Checking and adjusting the float

The float is responsible for the readings of the fuel level sensor. If the float is not adjusted correctly, the actual amount of fuel in the tank will not match the readings on the dashboard.

Checking the float is very simple - just fill the tank full and make sure that the readings on the instrument panel match the actual amount of gasoline in the tank. And if, as you drive, the fuel quantity arrow gradually drops, this indicates the serviceability of the float.

The correctness of the fuel level sensor readings depends on the correct position of the float

The float is adjusted in the following way:

1. The rear seat is removed from the interior.
2. The trim above the gas tank flap is bent.
3. The fastening bolts are unscrewed and the hatch cover is removed, under which the fuel pump is located in the tank cavity. There is a float on the pump cover.
4. The ignition turns on without starting the engine.
5. The float spoke is moved to the extreme right position. The fuel level arrow on the instrument panel should drop to zero.
6. If this does not happen, the float is adjusted until the instrument panel shows zero fuel level.
7. The float spoke is moved to the extreme right position, which should correspond to the readings of a full tank. If this does not happen, the float is adjusted in the same way.

Replacing the protective mesh

A protective mesh installed on the fuel pump filters the fuel entering the tank. It traps the largest particles of impurities and dirt.

Accordingly, the mesh quickly becomes clogged, and therefore the pump does not receive the required amount of fuel. The driver can understand that the mesh is clogged by the characteristic “sneezing” of the engine and a decrease in the dynamic properties of the car.

Replacing the mesh is quite simple:

1. The rear seat is removed.
2. Under the casing there is a gas tank hatch.
3. The bolts are unscrewed and the hatch cover is removed. Access to the fuel pump is provided.
4. Carefully disconnect the fuel lines and power plug.
5. The pump is pulled out of the tank. On some models, the hatch hole is smaller than the diameter of the pump, so it is expanded in some way (sawed out, cut with metal scissors).
6. The mesh secured with plastic clips is removed from the top of the pump.
7. The new mesh is lubricated with gasoline and installed on the pump.
8. Assembly is carried out in reverse order.

The fuel pump mesh traps the largest particles of impurities

Replacing the neck

The filler neck is usually made of metal, is susceptible to corrosion, and is replaced more often than the fuel tank itself.

Sometimes a rubber hose is installed instead of a neck

Removal of the neck may be difficult due to extensive corrosion. The process for replacing it is as follows:

1. Gasoline is drained from the tank or the engine is running until it stops due to lack of fuel.
2. The car is lifted with a jack.
3. The right rear wheel is removed to provide access to the neck. All joints are treated with WD-40 and left for 10–15 minutes.
4. The metal clamps securing the neck are unscrewed (they can be cut off with metal scissors), and all hoses are disconnected.
5. The neck is pulled out from under the car.
6. The place where the neck connects to the tank is cleaned of dirt and rust.
7. A new neck is installed and tightened with new clamps.
8. Fuel hoses are connected.
9. The right rear wheel returns to its place.

Repairing leaks

The most unpleasant and dangerous malfunction of a fuel tank is the appearance of holes or holes through which gasoline begins to leak. Holes invisible to the eye can be found by traces of fuel on the tank.

If traces of gasoline constantly appear under the car, this is a clear sign of a leaking gas tank.

Usually such faults are eliminated by soldering. For this you will need:

• soldering iron (500 W);
• iron (for heating the tank area);
• light alloy solder;
• soldering acid.

The smallest holes can be soldered without patches - the leak site is cleaned, degreased and filled with solder. Copper patches are applied to large holes and soldered around the perimeter.

In any case, after work you will need to cover the entire soldering area with bitumen mastic with anti-corrosion properties - this way the integrity of the tank will be maintained longer.

Causes of gas tank damage

Naturally, there can be many reasons for mechanical damage. However, it is worth mentioning the most common ones:

1. Corrosion;
2. Bloating due to high blood pressure;
3. Deformation or ruptures due to an accident;
4. External mechanical factors.

All reasons except the last one are obvious; as for the fourth point, it is due to the location of the fuel tank.

This means that in many cars the gas tank is located under the car and one of its sides is perpendicular to the ground.

In this case, stones flying out at an unpleasant angle, the bottom touching bumps or debris on the road can lead to some damage to the fuel container, but even in this case it can be repaired, for example, by soldering it.

Fuel tank repair

First of all, before you begin, you need to understand that although the process of repairing a fuel tank is not very complicated, you must adhere to the mandatory precautions and be extremely careful at some stages of the work, so you can avoid possible troubles and reduce the risk to life .

First of all, when starting repairs, the owner must drain all the fuel from the tank, to the last drop. To do this, you can use a regular rubber tube, but if the process is inconvenient, use a jack, tilting the car in the desired direction.

Soldering the fuel tank

Now it is necessary to assess the degree of destruction, and this degree is divided into two points:

1. Normal dents, no fuel leaks. In this case, you can level the walls of the tank by supplying compressed air inside.
2. Damage to the tank with fuel leakage. Let us dwell on this point in more detail, since it poses the greatest threat.

So, the first thing to remember is that under no circumstances do you weld immediately after draining the fuel. The tank can also be sealed only after time has passed. This is due to the fact that explosive fuel vapors are stored in the gas tank, which detonate when heated, and this is extremely dangerous.

To seal the tank, you need to rinse the tank thoroughly and fill it with water. Rinse with hot water and detergent. If you decide to solder the tank using tin solder, then you don’t have to fill it with water, since the temperature will not be high. However, such soldering is suitable only if the damage is small.

If the gaps are larger and hot soldering with fire is required, be sure to fill the tank with water, but in the place where you want to solder the gap, you must leave a small pocket of air by tilting the gas tank accordingly. At the same time, when carrying out soldering, do not close the lid of the fuel container under any circumstances, since the gas formed during heating must escape freely.

Conclusion

So, as you can see, there is nothing complicated in repairing a tank, and although this text presents only one of the methods that allows you to solder a tank, the other methods are also not particularly difficult. The main thing in this matter is to follow the precautionary rules prescribed above, otherwise the consequences can be severe for both man and machine.

DIY car gas tank repair

A car breakdown can happen anywhere. If you notice that the fuel tank of your car is leaking, then the problem must be partially eliminated on the spot. This way you can get to either a service station or a garage, where the problem can be completely eliminated. How? The answer is given below.

General safety rules

If the fuel tank of your car starts to leak, and you decide to carry out the repairs yourself, then you need to adhere to the following rules:

• Before starting repairs, drain all fuel (put the car on a jack and drain the gasoline using pipes);
• Dry the fuel tank thoroughly;
• If necessary, remove the tank (it all depends on the location where the hole occurred);
• Check the entire tank to see if there are still holes somewhere.

Plastic gas tank

Most often, in plastic gas tanks, longitudinal cracks appear on the body of the tank itself or at the place where the tank halves are welded. There are several ways to patch such a container.

Cold welding

Whether it will be possible to repair a fuel tank by cold welding depends on what kind of plastic the tank itself is made of.

If soft plastic was used, then it will be more effective to solder the hole, since cold welding will not “fall” due to poor adhesion of such plastic. If the plastic is hard, then you can safely buy cold welding.

Use it according to the manufacturer's instructions. Car owners do not give a clear answer as to how durable such treatment will be.

Remember! When sealing a hole in a fuel tank using cold welding, it is very important to thoroughly dry the surface to be treated.

Before applying the weld, you need to clean the surface of the tank so that it is clean, slightly uneven, so that the adhesion is more reliable.

Cold welding must be labeled as “gasoline resistant” on the packaging, otherwise the work will go down the drain.

Adhesives (sealants)

To seal a plastic gas tank, you can use fiberglass and epoxy resin. Before sealing, clean the surface, then apply a layer of fiberglass and impregnate with resin. Allow the surface to dry, then repeat the procedure. At the very end, treat the surface with an anti-corrosion agent. The entire procedure may take you about 4 hours.

If such a problem happens to you on the road, you can use Moment superglue and a piece of rag to seal it. You need to saturate and apply layers to the hole one by one. This method will help you get to the nearest service station.

Hot soldering iron

The most effective repair method is to solder the gas tank, even if it is plastic. For this you need:

• Soldering iron (200 W power);
• A piece of plastic;
• Alcohol ;
• Metal mesh (1 mm pitch);
• Sandpaper;
• Brush;
• Metal scissors;
• Electric jigsaw.

Important! When sealing a plastic gas tank, you need to use the same plastic from which the gas tank itself is made. Otherwise, different types of plastic will not connect, and the flow will continue.

Soldering the fuel tank occurs as follows:

1. Using metal scissors, cut out the desired piece of mesh;
2. Sand the surface;
3. Wipe the mesh and surface with alcohol;
4. Heat the soldering iron, place the mesh on the plastic, solder it (hold for 2 - 3 seconds, both materials should be connected, it is not necessary to fuse the mesh completely);
5. Clean the patch, degrease it, apply it to the hole and start heating it (the patch needs to be completely fused with the mesh and the tank);
6. Hold the soldering iron for 3–5 seconds, otherwise the plastic will be pressed through, and after the patch has cooled there will be no more holes.

How to make a gas tank with your own hands

The life of a driver is sometimes difficult - the road is fraught with many surprises.

However, most of the troubles arise due to problems with the “iron horse”: an overheated engine, a broken wheel or a muffler that suddenly fell off - the list of such force majeure can be continued indefinitely. One of these problems is a gas tank that is broken on the road, and this article will discuss how to fix this problem.

https://www.youtube.com/watch?v=_q3xPeWyBzcu0026t=32s

Damage to a gas tank is a truly unpleasant occurrence, and if a fuel leak is detected, it is necessary to urgently take measures that will allow you to get to a service station for quality repairs or replacement of the tank . The problem will have to be solved quickly and competently: you cannot wait for help and waste precious fuel, and the nearest populated area may be too far away.

You can notice a fuel leak by several signs:

• a sharp smell of gasoline in the car interior;
• a puddle of gasoline directly under the gas tank;
• rapid lowering of the fuel level sensor needle;
• excessive increase in fuel consumption.

Loss of fuel is a signal that you need to look for and eliminate the breakdown.

The situation is simplified by the fact that a gas tank with holes in the upper part will still allow access to the workshop, and if there are holes at the bottom of the tank, it will not be difficult to notice them.

Usually they occur at the bottom: the cause can be, firstly, various mechanical influences, and secondly, corrosion, corroding the tank on both sides.

Having identified the problem area, you urgently need to patch it using one of the available methods.

Cold welding gas tank repair

The most common way to repair a gas tank with your own hands in the field is cold welding.

The same method is used by specialists in auto repair shops to bring the tank into proper condition.

The repair process itself will look like this:

• first, use sandpaper to clean the damaged area (if this is not done, the applied patch will soon fall off);
• Next, a mixture of epoxy resin and hardener is prepared (you can use a heated engine to heat the mixture);
• Having soaked a fabric patch with the resulting mixture, it must be applied and pressed against the tank.

How to patch a plastic gas tank

Method one - patch the gas tank with epoxy glue

Drain the gasoline from the tank and let it dry. Sand the area around the hole or crack and wipe it down with an alcohol-soaked rag.

Mix 2 parts epoxy resin and apply around the entire perimeter of the hole. Cut the fiberglass patch wide enough to cover the hole and seal it off.

Place a fiberglass patch over the entire diameter of the hole and press the epoxy resin to cover the fiberglass. Apply more epoxy to the area and apply your patch, press down with something and let dry.

After drying, you can carefully clean it and apply paint to match the color of the tank.

Repairing a plastic gas tank using a special plastic soldering iron

Buy or rent plastic welding.

Remove the plastic gas tank from the vehicle and place it in a safe location for welding. Drain the gasoline from the tank and let it dry both inside and out. Wear safety glasses, a welding helmet, and welding gloves.

Use a plastic welding rod made specifically for this purpose and fill the crack or hole with liquefied plastic. Start at the edge and work your way all the way down the length of the crack or hole. Fill it with a little extra plastic and then sand it down.

Let the weld cool, sand it and, if desired, paint it with plastic paint.

If your hole is really huge, then it’s easier to replace the plastic fuel tank on your car with a new one.

Design and types of fuel tank for a motor boat

A standard fuel tank for outboard motors usually consists of several components, namely:
This configuration is common to all types of gas tanks. The fuel is poured into a container, which is closed with a special lid equipped with a vent valve or fitting. This is due to the fact that when exposed to sunlight and elevated temperatures, the gasoline in the tank begins to evaporate and its vapors create excess pressure, which poses a danger of ignition of gasoline vapors. Excess pressure is released using a device mounted in the gas tank cap. Using a connecting hose, fuel is supplied from the tank directly to the outboard motor. The volume of the tank is determined based on the power of the motor installed on the boat.

Varieties and classification

There is a division of tanks for outboard motors according to design features into the following categories:

There is also a division of gas tanks into soft and hard. Soft fuel tanks are made from special impermeable materials with increased elasticity, ensuring the tightness of the tank container. When the tank is filled, they stretch, and as gasoline is used, their size decreases. The advantage of this type of gas tank is the fact that gasoline vapors do not accumulate in them. Small dimensions and the ability to change shape allow them to be installed in places where a conventional rigid tank simply will not fit. The main disadvantage of such a tank for a motor boat is its high price.

As for the shape of the fuel tank, they are usually made either in the form of a canister or as a rectangular tank.

Based on the material used, gas tanks are divided into the following types:

All materials must be petrol resistant. Fabric (soft) gas tanks are made from multi-layer polymer fabrics that provide the containers with tightness and chemical resistance to the aggressive effects of gasoline.

Features of choice

The volume of the fuel tank is determined based on the power of the outboard motor installed on the boat. Very often, people who make long trips on motor boats (fishermen, tourists) are faced with the question of increasing the capacity of the gas tank.

There are several options to solve the problem. You can install an additional fuel tank of greater capacity, take with you a supply of gasoline in cans, etc. But such a solution to the problem implies an irrational use of free space, of which there is already little on a boat or boat.

The best option is to install an additional gas tank on the transom of the boat; this saves space and prevents the tank from moving on the wave. On inflatable boats, such a tank is mounted on a suspended transom, on PVC boats - on a stationary one, and on boats and rigid boats - on the stern. Some craftsmen install several flat containers connected to each other by tubes under the flooring on the bottom.

It should be remembered that when choosing a fuel tank, you need to pay attention to the following points:

DIY car gas tank repair

Installing a plastic patch using a soldering gun and special hot glue.

Drain the gas tank and wash it inside and out with soapy water. Lightly sand the perimeter of the area to be repaired.

Cut a piece of plastic larger than the hole, made from gas tank-like material, slightly larger than the repair hole.

Heat up the electric soldering gun, apply your patch and completely go over the contour of the cut plastic with a soldering gun with special hot glue, check that the glue completely covers the edges of the patch and is well sealed to the plastic of the tank itself.

You can also additionally apply epoxy resin or solvent-resistant glue along the contour for greater reliability of the weld.
