 Topic: Allis Chalmers c rusty gas tank

So I'd like to hear any sound advice from anyone on here that has been able to remove as much rust from inside the tank as possible. Any cool tricks would be great

I've posted the same question before myself. I got a lot of good advice, and tried about all of it except filling it with rocks and strapping it to a back wheel and driving around. I was afraid it would fall off and I would run over it with my luck. I usually use a short piece of log chain to shake around in it. If you got a way to rotate it would be even better. Then I fill it with water and put a pint of muriatic acid and sit over night. Then rinse it out good with acetone. The problem is, the rust is like a cancer. It keeps coming back. I put that blue coat stuff in my B tank and put a one inch stand pipe in it. I hadn't had much problems since then, but I've been told that coating will turn to goo after a while.

I'd like to know more about that electrolysis myself. What is it, and how is it done?

Some Radiator shops service and clean fuel tanks. You might want to check in your town to see if the local Radiator shop offers that service. If they do, its well worth the money to have it tanked out, sealed and any repairs done. No messin' with acids, chains, and whatever. You get back the cleanest tank possible and they usually seal it for you to! Around here, they charge $100.-$150. bucks. Well worth it in my opinion...

Yes I did put a rod down inside. Used a piece of rebar. I put a funnel in the neck of the tank to act as an insulator to keep the rebar anode from shorting to the tank. Clipped negative lead to tank, positive lead to rebar anode. Filled with water and washing soda solution. Used 1 tablespoon per gallon of water.
