On my 93 Toyota the gas tank is very rusty inside as noted replacing fuel pump. Outside is rust free. There are replacement tanks available but have a litany of poor quality complaints. One person is on their 5th after market replacement tank. There are no new OE tanks available. I can have a tank fabricated for $600, which I am told is a bargain!

So I have been looking at my options and interested in electrolysis. I have looked at many videos and read numerous articles about this and find one part confusing. When treating metal,say a tool, after the rust is removed a wire brush is used to remove the remaining black residue that is left on the metal. When using the process on gas tanks there is no mention of the black residue.

Why no mention of the residue inside tanks????

You might give this a try. It worked well for me on a 1986 Dolphin/Toyota Class C fuel tank some years ago.

U can have a radiator shop clean & coat your fuel tank or if’s you’re inclined you can get “ gas tank coating “ on Amazon or elsewhere. I urge you to clean your tank TWICE according to the instructions! If you don’t get the tank completely cleaned & completely dry before you coat your tank the coating can come off and you will have a major headache.... I used to clean fuel tanks for a living.

I've done motorcycle tanks using POR-15. It's a bit of work but I see they also have an auto/truck kit.

thanks for the responses. The sump has 2 small channels under it, which I assume it to keep fuel from rapidly leaving the sump. I believe I can clean the channels with compressed air before the tank sealer sets??

There is a 1/4" line exiting the tank which I believe goes to the charcoal canister, inside the tank it is connected to an odd thingy. What is it, will tank sealer plug it? I do not have large hands but I cannot reach it. [image]
