## Discrepancy

DURING A ROUTINE FLIGHT THE PILOT NOTED A FUEL SMELL DURING HEATER OPERATION.  HE SHUT OFF THE HEATER AND RETURNED TO MAINTENANCE BASE.  THE MECHANICS NOTED THAT THE HEATER FUEL PSI REGULATOR WAS LEAKING FROM DIAPHRAGM SEAL AREA.  A NEW VALVE WAS INSTALLED, BUT FAILED AFTER 2 HRS OF OPERATION.   A 2ND NEW VALVE WAS INSTALLED AND WAS FOUND TO LEAK FROM DIAPHRAGM AREA AFTER A FEW HOURS OF OPERATION.   THE THIRD VALVE WORKS NORMALLY.  NO LEAKS WERE FOUND.
