## Discrepancy

WHILE CRUISING AT 6000 FEET IFR FLIGHT PLAN (VFR CONDITIONS) THE FUEL PRESSURE GAUGE DROPPED FROM 14 PSI TO 6 PSI FOR A BRIEF PERIOD (10 SEC) AND THEN DROPPED TO ZERO WITH SUBSEQUENT ENGINE FAILURE (LOSS OF POWER). RESTORED ENGINE POWER BY UTILIZING BACK UP HAND PUMP FOR DURATION OF FLIGHT TO NEAREST APPROPRIATE AIRPORT AND LANDED WITHOUT INCIDENT. FUEL PUMP WAS REMOVED AND SENT FOR REPAIR. CURIOUSLY THIS WAS THE REPAIR STATION THAT OVERHAULED THE PUMP 119 HOURS PRIOR TO FAILURE. THE PUMP WAS RETURNED AFTER REPAIRING BY INSTALLATION OF THE FOLLOWING PARTS: PN'S RA 3791 SEAL DISK AND RA 7766 RELIEF VALVE.
