Fuel Pressure Fluctuations
I'm dealing with fuel pressure fluctuation on a Garmin G3X 4.0 to 6.2 every few seconds. Kitfox S7 with 912 ULS; return line installed. Engine RPMs are consistently stable and the measured psi is stable. I’ve read the SBs. Checked for fuel line leaks, loose connections and weak crimps - none. Re-crimped sensor connections - no joy. Considering replacing the Kavlico P4055-15G 0-15 psi sensor, but they’re no longer available. I checked the Garmin Installation Manual Table 21-1 for an alternate. In talking to Garmin about their 0-15 psi sensor I uncovered a part number error in their G3X Installation manual, but it still comes up with a different sensor with a much larger operational range.
Has anyone else experienced the problem? I'm looking for suggestions on how to proceed or an alternative part.
