## Discrepancy

FUEL CONFIG LIGHT ON WITH 1200 NR UNCOMMANDED TRANSFER TO CENTER TANK.  SEVERAL LEAKS WERE FOUND FROM THE LEFT MAIN TANK INTO THE CENTER TANK.  A LEAKING SCAVANGE LINE B NUT WAS CORRECTED BY REPLACING THE O-RING.  A LEAKING SEAL AROUND THE SURGE TANK, DRAIN LINE WHERE IT ENTERS INTO THE CENTER TANKS, WAS REPAIRED BY RESEALING THE AREA, AND LASTLY THE SURGE TANK DRAIN VALVE AND VACUUM VALVES WERE REPLACED.  AFTER ALL ABOVE ACTIONS, THE LEAK WAS CORRECTED.
