Have a diesel tank leaking .I'm not looking for reasons not to weld it just wondering if someone here has experience at this.If I don't feel comfortable with it i can farm it out.Just don't want to if I don't have to.I have a pressure washer one is heated if i need it.I would prefer not to fill it with water if i can do it safely another way.I can braze it,wire weld it or tig it.Thanks  al

NAPA has a very good epoxy fiberglass repair kit.  Fairly simple and quick, and has worked well for me.     Lazerdan

I have one experience with a fuel tank leaking and my mechanic asked me to rub a bar of soap into the crack in the tank. It stopped the leak till he got out to repair the tank, the leak was caused by vibration and he welded it up without removing the fuel. The soap was a good temporary fix and did stop the leak temporarily.

Slider, I've welded diesel tanks on heavy equipment by flooding the tank with an intert gas (such as C02 from a MIG welder.

I calculated the amount of cubic feet in the tank, and then ran a hose from the regulator to the tank and let it run long enough until the tank was full and the air displaced.  While welding, I left the regulator running as well.

I've also used the water method, but the gas was cleaner.

i dropped it off this morning .we cleaned it out first then they filled it with soapy water .they then put in a air line and on low pressure let it bubble all afternoon.this method is what they feel is safe.They were using a hose from a tailpipe of a running vehicle until they had one explode.

That is what we did when I was on the fire dept.  Gas tank on a auto would be leaking so we would put bar soap in the leak. Worked well until it was fixed.

Vehicle exhaust piped into the tank will also make it safe to weld.

I'd use an epoxy. That stuff is strong.  Another old method to fix a pinhole leak is to screw a sheetmetal screw, with a little gasket, on it into the hole.

I had a gas tank rust out on a pickup, it ended up being about a 4" hole in it. I fixed it with Liquid Steel and screen, worked perfect.
