Default Can't get Fuel pressure above 5.5 psi
Im running a holley pump part number 12-801-1 with Mallory 4309 fuel pressure regulator. It doesnt matter if i screw the hex head bolt in or out, the fuel pressure stays the same at around 5 psi while not running, but with the key on, and at about 5.5psi running.

Any suggestions?
