Ok, installaed new electric fuel pressure gauge. Gauge reads about 14 psi. Just sits there, no movement. Goes to 0 with power off. Goes to 100 psi if I remove the sending unit wire, goes to 0 if I remove the ground wire. This would seem the gauge is working. I'm on my second sending unit from summitt. Double checked all connections, even rewired twice. Sending unit is mounted at the schrader valve. I had a mechanical under hood gauge there before installing this gauge. Was getting normal readings prior to this install, so fuel pump is working properly. I am at a loss and ready to send everything back to summit. Anybody with some input that I may be missing would be greatly appreciated. Thanks.
