## Discrepancy

WHILE DEPARTING ATL, CENTER FUEL GAUAGE WAS READING 2500 LBS LOWER, WHILE RT WING GAUGE WAS READING HIGHER BY THE SAME.  TWO UNITS TRIM REQUIRED FOR LEVEL FLT.  AFTER RETURNING TO GATE, FOUND NR 3 TANK VALVE SWITCH IN THEOPEN POSITION DUE TO A BROKEN GUARD COVER ON THE WING REFUELING STATION.  ALSO FOUND THE DEFUEL VALVE DEFECTIVE.  TRANSFERRED FUEL ON THE GROUND WITH THE DEFUEL VALVE IN THE CLOSED POSTION.  REPLACED DEFUEL VALVE.
