If it's a S4 tank this one was in real nice shape before I had it done.

It just had some old gas in it. Im changing my car over to a carb, so I wanted it clean. Then I went with a fuel cell, now I don't need it.

It like having a new tank but better, it will last without getting crud/rust build up in your injectors.

pm me let me know.

 

yeah, ive got an 86 GXL and it has some MAJOR rust in the tank, its bad.

 

Electrolysis to remove rust then use a liquid liner to prevent future rust. Very time consuming. I'd go to a local parts yard and pull a rust free S5 fuel tank.

if you read my thread, you'll see that i was having some major issues due to a rusty tank. i replaced it once with a perfect rust free tank and it happened again. it cost me a brand new fuel pump and a huge headache. i never found the cause of the problem but everything has been fine since using the POR kit.
