I had to install a pressure regulator after upgrading my fuel line and fuel pump. My problem is the pressure moves from 5 psi to 9 and I am constantly having to change it. I have looked at the gauge when the engine is hot and cold and it does not seem to be heat related.The car does act flooded on startup some times like the pressure is over powering the needle and seat. Has anyone ever purchased a bad regulator?
