S3flyer Posted December 30, 2013 Report Share Posted December 30, 2013 I had the new Italian fuel pump installed at my annual approximately 4 flight hours ago. Don't actually recall the pressure readings but were all steady and over 4.0 for those hours. Went up today with everything safely in the green but on climb-out the pressure dropped slowly from 4.8 to around 1.9. I leveled off and the fuel pressure went back up to a steady ~4.5. I went up to 5500rpm in level flight with steep banks and the fuel pressure remained steady. Started a climb at full throttle and the pressure slowly dropped again. Landed and went through several 4500rpm run-ups and pressure varied between 4.5 and 5.2. The engine ran fine at all times. I have the Dynon Kavlico fuel pressure sensor remotely mounted. Checked the various grounds on my S3 and all were tight and clean. No detectable fuel leaks. Any ideas? Link to comment Share on other sites More sharing options...
