PA-28 Fuel Pressure
Has anyone experienced an issue with Warrior fuel pressure dropping to a low, but still well in the green, level for a few mins and then recovering to normal without apparent cause? This low pressure is instantly rectified by the electric pump and occurs in any stage of flight including taxying. Fitting a new mechanical pump doesn't fix it. Niether does changing tanks in flight.
I appreciate that many sites say "It's normal, live with it" but it's not normal in this aircraft. If it's caused by a restriction someplace, why would the fuel pressure settle at a steady, lower, level regardless of power setting and recover of it's own accord? Obviously the fuel lines, gascolator etc. have been checked for any contamination, which there isn't.
Any ideas welcome.
