white vinegar will do the same thing as evapo-rust for a fraction of the price.

Thank you Dan..

My filler neck was nice and clean. Also,i put the tank back in and got the car running and realized the little foam donut you speak of is something i forgot to install. I was wondering if it was necessary to help seal or just isolate it . Do you guys run that foam ring??

If the product you used dissolved rust, the metal is very likely thinner, especially where the rust was deep. One location to be wary of is the filler neck. As originally built, Mini tanks had a foam plastic donut around the neck, which absorbed moisture and rusted the neck from the outside. Mine was rusty enough to see light through. I used POR15, including their repair gauze for the neck. when using an inside coating, you have to remove the screen from the pick-up tube. Easily done by pushing a thin rod through the tube. Add a fuel filter when done. The good thing about POR15 coating is that you get much less (almost none) dirt in the fuel, which is mostly rust to begin with. POR15 will not flake of if the metal is prepped with their wash process.

Only thing im worried with is factory tanks sortve have a coating of some sort i assume and since this tank was soo crusty,im thinking it may get some slight rust above the fuel level . I will keep an eye on it. Im not sure how i feel about using any of the coating products in the tank to be honest. If it was a factory engine or even a stock D16 i wouldnt mind but it being a turbo d16 that i plan on pushing kindve far i dont want to risk particles flaking off and restricting my fuel feed.

Well,i picked up some Evapo-Rust from autozone. A gallon of it and put it in my Crusty fuel tank. Sealed off all the holes with rubber caps and a rubber glove and some tape on the filler neck and shook it really good and let it sit overnight in the bottom of my tank.Wow,that stuff works amazing.The tank looks brand new inside. I shook it around a few times and let it sit for a while and it cleaned out the whole inside of the tank. Anyone ever try that stuff? If not,give it a try! No fumes etc. Drained it out back into the jug and will re use it for other projects. Im completely amazed with that product.
