(I started this in just jets but this may be the proper place.)
Hey guys, i have a 130gph holley marine mechanical fuel pump that feeds through a barry grant fuel pressure regulator that splits dual fuel lines into a holley 850dp. the pump has 8an to the regulator and 6an from the regulator to the carb. the fuel pressure gauge. the fuel pressure with this setup was 6 1/2lb at idle and 5lb or less at full throttle with the regulator set wide open. i removed this set up and went from the pump to the carb with the same size lines. now the pressure is 7 1/2lb at idle and 8lb on the throttle.
My queastion is will i be ok with this pressure. i run a engine cover and dont want any suprises.I am sure not impressed with the $100.00 barry grant regulator.

9lbs is max before it forces by the needle
Thanks guys. I am going to run it. hopefully i will see a little more response with the higher fuel pressure.
