Fuel Tank Rust

[badbronco]

Ok you guys have prolly answered this 100 times. I have a fuel tank off a 110 that is great shape on the outside but has rust on the inside. How can I save this tank and use it?

Thanks

Welcome to the site Tim. On rusty tanks I use a tank liner called "Red-Kote". Unlike most other tank liners Red-Kote doesn't require you to remove all the rust before coating. It's always best to remove as much as you can, but you don't need to use any acid on the tank. It will even seal pin hole leaks pretty easy. I have done probably 20+ tanks and haven't ever had one fail. I have used other types with more problems than successes.

i just put a feul filter in line and use it.. has worked 4 me for many years .. but thats me

Howdy knows for sure.

Lots of options.
Blast with a pressure washer and dry it completely and just use it,
the older I get the more 40 bucks for the radiator shop to do it gets more appealing
to me.
When you get it how you want it, everyone says to keep them full and they simply can;t rust. No oxygen, no rust.

If you want a cheap effective way to remove the rust take the tank off and fill it to the top with vinegar (any variety I just get the cheapest). Let it sit for a day then dump the vinegar into a bucket (you can reuse it) and rinse the inside out thoroughly. If rust remains pour the vinegar back in but use a coffee filter to strain the crap out and let it sit for another day or so. I have cleaned the rust out of a number of tanks using this method.

And like pretty much everyone that will read this I was extremely skeptical when my old man told me about this, he claimed he used it to clean tons of motorcycle tanks. Well I tried it and about sh*t my pants when the tank looked brand new inside. Cheap, extremely effective, and incredibly easy. Plus no harsh chemicals and its reusable.

id try seafoam, its like a engine rebuild kit in a can, plus, it can be used in gas and to clean out your tanks

Sea foam does not remove rust. Muriatic acid will get the rust out but it's harsh, the fumes are dangerous. Vinegar works also, like mentioned above, I just used this method on a 70 tank. I let the vinegar sit in it for a few days and it came out pretty good.

seafiam worked on my grandpas boat tank just fine
