I have a Summit Electric Fuel pump with regulator set to 7psi idle to feed my 350 with a 650DP. These parts are less than a year old and I have noticed that sometimes when the car is started up, the fuel pressure will go up to 15psi (that's as high as the gauge reads) then if I hit the regulator with a screwdriver the pressure drops to normal. I've taken apart the regulator to see if the spring was messed up and everything is fine. Is this set-up no good? I was thinking of trying a new reg. but is the fuel pump at fault too? Should I have gone with a brand name in this area? Any help would be great appreciated.
