## Discrepancy

THE FLIGHT CREW REPORTED THAT WHEN USING FILL SWITCH T MOVE FUEL FROM WINGS TO FUSELAGE TANK, FUEL LEAKS OUT OF THE LEFT ENGINE DRAIN. THE MAINTENANCE VENDOR CONFIRMED DISCREPANCY AND DETERMINED THE NO1 ENGINE START/DUMP VALVE WAS LEAKING. THE START/DUMP VALVE WAS REMOVED AND AN OVERHAULED UNIT WAS INSTALLED. GROUND RUNS AND LEAK CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS THEN RETURNED TO SERVICE.
