Well actually the tank isn't the problem but the filler tube that connects to it might be. I have 2 in line gas filters with 40 micron screens the size of a quarter. The one closest to the tank keeps getting plugged up, 3 times now. The last time after only a 200 mile trip (since replacing the screen) Car started stalling like it was running out of gas. Took the tank down to flush it out and noticed looking up the filler tube that it seems to be rusting on the inside ever so slightly. I have Aeroquip blue rubber hoses leading up to the front but I don't think these are degrading as they are made for this and the front filter seems to stay much clearer. There doesn't seem to be any water in the gas because when the filter gets replaced it runs great. Any thoughts as to what I can treat the inside of this filler pipe with so it won't rust? Has anyone ever seen a single rubber hose leading from the gas cap down to the tank? Don't know if that would work because of the overflow tube.
Space is real tight so a canister filter is out of the question.
Thoughts please....
