I have a magnafuel prostar 500 fuel pump with a quick fuel regulator and for some reason my fuel pressure creeps up and will actually peg the guage out while idleing. this is the second regulator i have had on here that does this. If i remember correctly I have the fuel pressure coming from the pump set to 27 lbs and the drops to 6 on the quick fuel regulator. 10an line to the front and the bypass off of the pump like magnafuel shows it. What is causing this? do I need to lower the pump pressure more? or get a different regulator?
