Best Methods to Seal a Small Leak in a Metal Fuel Tank Caused by Mechanical Damage

Question

Hello. I have a question if anyone knows any good way to glue the fuel tank (metal tank), because this morning I noticed a small leak on the tank. I will just add that it is not to blame for corrosion and the hole was caused by mechanical damage. Regards

Zwierzak81 · Answer

I would suggest a glue like poxilina. I just don't know if it will react with gasoline. There should be something written on the packaging about contraindications

ankuch · Answer

You did not write where the hole is, if it is on the weld, the matter can be complicated.
If on a straight cover, "Poxipol" or "Distal" will be good.
However, the surest thing will be soldering - only for tin and only with a soldering iron.
Before that, rinse the tank several times with water.

Write how big this tank is. I do not think that with the soldering iron you managed to heat the tank enough to tin the leakage point. I welded mine with a migrate.

bula · Answer

Hello. It is a diesel tank and the hole is on its underside, so it is not a weld point, but a smooth surface. I was also thinking about soldering, but I don't know if this metal can be soldered.

Hello, I suggest welding with migomat, possibly tin, and with adhesives and other crap, give it a rest because it will be a temporary removal of the leak, best regards

ankuch · Answer

In the absence of practice, I would not advise you to repair with a migomat, although the risk is slightly lower after diesel fuel.
As for the material of the tank, if it is metal, I have not come across anything other than steel. Sometimes it can be galvanized or even tinned.
Gluing the diesel tank is actually difficult, you need to thoroughly degrease it.

platypus I do not agree with you!!! Two years ago my diesel fuel tank was leaking at the weld and I glued it with two-component glue / I don't remember its name / specially designed for this purpose - holds to this day. I've already glued several fuel tanks, and I find the use of glue to be much safer than welding. In addition, the glue fills the gap precisely. I have been using for this purpose recently poksillin - it is perfect and can be profiled because it behaves like plasticine. It is only important to clean the gluing place very thoroughly and degrease it. I think it's worth a try !! Regards Peter36

In my workshop, it is done like this: the fuel is drained and if the tank is pulled out, it is flooded with water (large tanks sometimes splash), if in the car a hose is connected and the exhaust gas is injected and the tank is treated with a burner (the latter method is not suitable to gasoline)

4 years ago I covered a small hole with poxipol and it still holds it today, the mechanical damage was a gasoline tank. After the oil, it will be difficult to degrease, especially from the bottom, unless you remove the tank.

rafka10 · Answer

it is better to spray gas, but you have to turn the fuel tank over and fill it with water (otherwise it will be a big BOOM ) it is for sure

rafal149135 · Answer

I do not want to open a new topic and I also have a problem in Iveco with the tank, how can it be glued? As far as I know, it is made of plastic

kwok · Answer

poly resin and glass mat there are such kits in moto stores or if you do not find it, at least resin putty with fiberglass

I repair metal tanks as follows: The leak is known to be cleaned
and degrease, then cut a patch from a copper plate 0.3 mm thick or similar
I use a soldering iron to coat the tank with a soldering iron, phosphor is useful then it catches better
then I press the tin on the patch and solder it together, paint over the whole with a preservative.
Plastic, I recommend welding plastic in workshops where they regenerate bumpers.
I warn against welding by cutting. A friend was cutting the Zerwało tank with a contour
his head :cry:

robokop · Answer

Nothing - you can try to take it to a bumper welding specialist, maybe he will. The material is extremely nasty and resistant to any adhesives, including polyester / epoxy resins.

manta · Answer

Plastic welder suitable material, most work on cleaning. Then control of 0.5 bar pressure + water with detergent.

fabians · Answer

As for the metal tank, I was recommended by a mechanic friend to use the anaerobic compound "VICTOR REINZ REINZOSIL SILICON SEALING MESS". One similar to silicone, resistant to oils fuel etc. I had the problem of a leak on the weld of the ON tank. Rust had been pitting for years and a leak had developed. I used a screwdriver to clean off the rust and then applied phosphoric acid as a rust remover. After doing 3-4 of these and running the fuel out to 1/4 tank, I degreased and applied the product. After 3 days I poured to full, zero leaks. I applied epoxy primer to the surrounds and repainted with maintenance.
