I think I need a new fuel pressure sensor. Shortly after a refueling stop with 100LL, the fuel pressure started to swing rapidly from 1.1 to 5.0 psi at 5400 RPM and suddenly stopped at 0.0 psi. Engine was running fine. I made a precautionary landing to check out the problem.
On the ground I determined that I had fuel pressure that wasn't registering on the G3X. I could hear the electric pump running and tested the flow from the gasolator to confirm the pump was indeed working.
It was very hot out and I decided to let the engine cool for a couple of hours. When I powered up the G3X the fuel pressure showed max fuel pressure 14+ psi. As soon as I started the Rotax, the fuel pressure started to swing up and down and stoped at 0.0 psi.
I unplugged the sensor, removed the rubber seal and reattached the plug with no change in the reading.
After extensive taxi testing and run-ups I finished the flight.
I will order a new sensor unless some one has had the same symptoms and resolved it using a different method.
