## Discrepancy

DURING ALL OPERATIONS, NOTICED VERY ERRATIC FUEL QUANTITY INDICATIONS FROM BOTH TANKS.  DURING ANNUAL INSPECTION, MECHANIC DISCOVERED THAT THE BOTH FUEL QUANTITY SENDERS RESISTANCE WAS VERY ERRATIC AND DID NOT APPEAR TO BE WITHIN TOLERANCE.  FUEL QUANTITY SENDERS HAD BEEN REPLACED WITH O/H UNITS APPROX 40 HOURS PREVIOUS.  REPLACED WITH NEW PMA UNITS AND OPERATION NORMAL. THE O/H UNITS DID NOT APPEAR TO BE ANYMORE THAN OEM SENDERS THAT HAD BEEN CLEANED UP.
