## Discrepancy

TROUBLESHOOTING REASON  FOR SPORADIC/INTERMITTENT FUEL FLOW INDICATIONS.  FOUND FLOW WAS LOW AND WAS CHANGING - FOUND MECHANICAL FUEL PUMP SEAL FAILED ALLOWING ENGINE OIL TO FILL MOST BOTTOM CHAMBER OF PUMP BELOW LOWEST DIAPHRAGM.  SUSPECT THAT THIS WAS NOT ALLOWING DIAPHRAGM FULL MOVEMENT AND THUS RESTRICTING FUEL FLOW.
