## Discrepancy

AFTER COMPLETION OF A PHASE INSPECTION, FOUND THE LT FUEL BOOST PUMP WAS NOT OPERATING.  REPLACEMENT RECEIVED & INSTALLED, THE OUTPUT PRESS FAILED TO REGISTER ON THE FLIGHT DECK INDICATOR.  CONTACTED THE VENDOR FOR A RMA & RECEIVED ANOTHER FUEL BOOST PUMP.  AGAIN, ONCE INSTALLED IT FAILED TO PROVIDE PROPER PRESS, THOUGH THIS ONE DID INDICATE.  WE HAD THEN REMOVED A SERVICEABLE FUEL BOOST PUMP FROM ANOTHER ACFT & AT THIS TIME ALL FUNCTIONAL & LEAK CHECKS WERE SATISFACTORY.  THE SECOND PUMP RECEIVED & DID ARRIVE WITH THE TEARDOWN REPORT & WAS SENT IN FOR THE EXACT REASON IT FAILED ON INSTALL.  THE 8130 SHOWED THAT THE UNIT WAS OVERHAULED.  THE FIRST FAILED PUMP RECEIVED WAS SN 10AM151 & WAS OVERHAULED AS WAS THE SECOND PUMP SN 2M131.
