S3flyer Posted May 14, 2012 Report Share Posted May 14, 2012 My fuel pressure has read lower than my normal the last couple flights. Symptoms: My normal cruise reading is in the 3.5 to 3.9 range Now reading 2.9/3.0 at 5000 RPM Went as low as 2.8 in a full power 3000' climb Pressure goes up when throttling back Pressure is around 3.3 at idle The readings are steady ( not bouncing around or drifting one way or the other) Gascolator is clean Engine is running well Switching on the aux fuel pump does not increase the pressure (my plane is a Sting) but it is working Fuel pressure sender and/or connections? Is the sender the same VDO component as the oil pressure sender? I'll be working on it this weekend but was looking for likely candidates to check first.
