## Discrepancy

AT FL340 DURING A CROSS FEED OPS TO CORRECT MINOR FUEL IMBALANCE THE LEFT ENG ROLLED BACK TO 52 PERCENT N1.  LEFT MAIN BOOST PUMP WERE TURNED BACK ON AND X-FEED VLV CLOSED.  ACFT RETRIMMED AND A/T ARM SW TURNED OFF.  INITIALLY ENG WAS UNRESPONSIVE TO CHANGES IN THROTTLE POS.  REFERRED TO QRH FOR ENG SURGE/STALL AS THROTTLE WAS RETARDED ENG INDICATIONS FOLLOWED NORMALLY.  ALLOWED ENG TO IDLE FOR 2 MINS THEN SLOWLY ADVANCED PWR TO CRUISE THRUST.  ALL INDICATIONS NORMAL.  PERFORMED SUCTION TEST.  ALL OK.  REPLACING ENG FUEL PUMP AND PERFORMING HIGH POWER RUN.  MAINTENANCE IN PROGRESS.
