Hi gang, I need a little help diagnosing a problem. The fuel pressure readings on my Dynon D-180 started fluctuating all over the place and I?m constantly getting a ?high fuel pressure? alert. The engine is an IO-360 180/HP. equipped with both a mechanical and electric fuel pump along with a red-cube. The engine is running fine and all connections appear to be secure. There?s no rhyme or reason as to when the high pressure alarm goes off. It does it LOP in a low power cruise configuration just as often as it does on takeoff with the electric fuel pump running with high power settings. When I?m looking at the fuel pressure gauge on the EMS page I?m getting constant fluctuations ranging from about 10 psi. all the way to about 40 psi. and it never settles down to any particular steady reading. Like I said above, all connections appear to be good, so where do I start? Fuel filters? Sender? Air trapped in the line? Thanks in advance.
