I'm New Here
Setup is RV-14A with first generation EFII. This system has a fuel return line, and fuel pressure is regulated by an aeromotive fuel pressure regulator and monitored by a Kavlico 150 PSI sensor that sits on said regulator.
I have had issues with high indicated fuel pressures before and exchanged the sensor, which dealt with the issue. That was about 50 hours ago. Now, on my last flight, I observed again steadily rising fuel pressure, reaching as high as >70 by the time I landed. Engine ran perfectly fine, fuel flow normal. After I shut down, fuel pressure stayed >50 (?), so I pulled both fuel pump breakers and cranked the engine again so as to make sure there is no residual pressure in the system. It still read >50. My guess is that I have another bad fuel pressure sensor.
What I don't like about this is that the sensor is only about 50 hours old. Anyone else got similar experience? Ideas?
