Rust inside the gas tank. Is there a solution?

Scalpel · Post by **Scalpel** » Mon May 19, 2008 4:39 pm

I pulled the gas tank off my 89 Elite, and discovered why the gas wasn't flowing well: half a cup of rust. I managed to get most of it out of the tank, but I'm obviously pretty worried about future rust development.

Is there any sort of additive or spray that will seal or neutralize the rust so that I can still use this tank? The replacement tank is priced at around $100, and that's not money I have available to spend.

go get like 10 bran new nuts and bolts and a gallon of gas, put some gas in it and the nuts and bolds, close the tank up, shake for about 5 min empty and the repeat five or six times or till all the rust is out

I'm going to attempt the following steps:

1. Fill the gas tank with some water and a bag of glass marbles, and shake the heck out of it to scrub the rust out.

2. Rinse it out thoroughly.

3. Dump a bottle of Evapo-Rust into the tank, swirl it around, and let it sit for a couple days.

4. Remove the Evapo-Rust and hopefully all the rust.

I'll let you guys know how it goes.

You could always just Kreme the tank and never have to worry about rust again.

I'm assuming that's some sort of tank coating?

Part of the problem with this process is that I can't seem to get the fuel gauge assembly detached. The screws holding it in are stuck tight, so I need to either drill them out and get new screws, or fix this without removing the gauge.

This gas tank issue is turning out to be twice as much of a pain as the carb, which was actually easy and a lot of fun.

I personally don't like Kreme; it won't remove the rust and ends up flaking off into the gas. It's only to be used to salvage a rusty and leaky tank, which should just be replaced anyway.

Cleaning a tank should take about 2 hours tops if you follow my instructions.

Really? I've never had a problem with it coming off.
