I have changed the fuel pump with an evo 8 pump. New install kit with new sock. 6an line to the filter. Fresh gas. New oem fuel filter. The crud and nasty fuel came out of the old fuel filter.
I'm running a stock fuel pressure regulator. I have 3 of them and have tried all of them on.
Yes but if the problem was in your fuel tank, changing all that wouldn't eliminate the problem. How did the old sock look?
Anyway, still think checking base fuel pressure is your next step. If it's low, the fact you've tried 3 means the problem is not likely the regulator.
