J20A Engine - Measure Fuel Pressure?
#5
I received the parts and have them installed. Perfect fit!

Next question...
With the pump on I set the fuel pressure to 35psi (engine off). As soon as the pump is turned off, the pressure instantly drops to 25psi. Within 60 seconds it goes down to 0psi. I thought the system was to remain pressurized (for a least a minute) when the pump is turned off? I checked the system (hoses) and did not find any leaks. Pinching the return line...the pressure remains at 24psi for 1 minute.

I'm using a Mallory 4305M FPR...
