BEFORE DEPARTURE,  HAD BOTH MAIN TANKS SHOWING FULL WITH CTR FUEL BEING USED FOR T/O AND CLIMB.  AT TOP OF CLIMB,  ENTRY CRUISE,   NOTED THE RT MAIN TANK SHOWING 7.96 WITH LT MAIN STILL SHOWING 8.58.

FQIS BITE SHOWS NO FAULTS OR FAILS IAW FIM 28-41 TASK 801,  COMPARISON CHECK OF NR 2 TANK INDICATOR WITH STICK WITHIN LIMITS IAW AMM 28-41-00 720-801. OK FOR SERVICE.
