Not Ranked
hmmm. the Holley BLUE comes with an external / separate fuel pressure regulator. however, the the Holley RED electric fuel pump is supposed to be self regulated by Holley to 7 psi with no separate fuel pressure regulator. and yet you got a 8 psi reading ? maybe it is a variance in the gauge ? you should be alright at 5-7 psi for those cubes and carb at high rpm's under heavy acceleration. bill.
