At 245 tach hours I replaced the fuel pressure sensor (41,315) from Advanced Flight Systems as it has begun to stick indicating fuel pressure even when the engine was not running. Confirmed it was the sensor by tapping lightly on the unit and seeing fuel pressure drop to zero. All was fine with the new sensor until @ 15 hours of tach time when the new unit started showing similar behavior. At annual I cleaned all filters & screens in the fuel system and did not find anything out of the normal. Anyone else having this problem or any ideas? I was a little troubled that the first unit failed after a fairly short life but with this unit going I'm wondering if something is amiss.
