I'm am perplexed with a high fuel pressure issue.
My Rotax 912 ULS was shipped to me in March 2016. First flight was in January 2017. I'm using the G3X system. I have 50 hours on the airplane.
On my last flight I had unusually high fuel pressure readings. It came on suddenly and hasn't gone away. I can't tell if I have a bad fuel pump, an electrical problem, a plugged carb/gascolator, or something else.
Below is graph showing the fuel flow and fuel pressure over the 1.5 hr flight from Vernal, Utah to Salt Lake City. Given the constant fuel pressure warnings, I pulled the fuel pump fuse once I had reached altitude. You'll note that fuel pressure stabilized within the "green" when the fuel pump fuse was pulled, but it was still erratic. What is really perplexing is the decrease in fuel flow once the pressure increased at the end of the flight.
Any ideas on where to start?
