Do you have a return side pressure regulator valve installed .... I had the same problem even running a belt drive fuel pump .... installed one and was able to maintain fuel good fuel pressure all the way down the track.
as far as on the back side of the p pump?
no I do not, just the overflow valve?
can you explain more about this please?
