Fuel pressure question
Fuel pressure question So I have the squash fuel pump system, Holley fuel rails, aeromotive boost regulator. When I turn the key on watching my fuel pressure gauge it goes to 60 and slowly falls to zero . Shouldn't it hold some kind of pressure ? When the car is on the fuel pressure is good just wondering if this is normal, or if the boost regulator is bad. I have to turn the key to the on position for 3 seconds. Then turn it over to start thanks guys.
I am dealing with the same issue on my Racetronix setup.
I was told to check:
Fuel tube not sealing or compromised
Regulator leaking down
Fuel injector leaking down
Fuel pump check-valve leaking down
In my case it appears to be the check-valve in pump as everything else checks out okay.

Ok so its something that i shouldn't worry about then? I thought if the key is on and car not running it should hold some kind of pressure.
