Does a good gas tank need to be sealed

[Guest]

Despite people's advice I put cream tank liner in my tank because I already have it. In a month it's already gone bad I don't think I neutralize the acid enough so it's rusting and spots is it a bad idea to just remove the tank liner and not have one at all

I would never coat a tank that's not rusted. If you can get the coating out then that is what I would do. Assuming that your tank was in good shape originally and the tank coating didn't screw it up.

Well there was some sort of tank liner in there before and that started coming off otherwise the tank seemed in good condition

[JTGS850GL]

What condition? Rust?

[Kman123]

No there wasn't rust until I did the acid washed to etch the tank, then it flash rusted but I cleaned that up and thought I neutralize it, but I believe there may be some rust under the liner

[JTGS850GL]

If you have rust under the liner then you need to get that liner out and remove the rust. Otherwise, you will have more trouble/

Okay will I be okay to leave it just Steel I've heard about people using 2-stroke oil to coat metal would that work

Just make sure that you keep it full of fuel or coat it with some WD40 if it's not going to be used right away.

I have never had a tank rust out on me
I remember as a boy my dads trucks had scratched and exposed boxes but as he always had a barrel of diesel in the back the things never rusted.
Wonder of a tank of diesel prperly drained after storage would keep a tank spotless
the thin film on the pickups kept things fine. Maybe it was a high sulphur content but in moisture that would make for strong acid and etch the heck utta things.
I miss them old fords
damn
