## Discrepancy

FUEL SEEMS TO TRANSFER INFLT FROM RIGHT WING TO LEFT W- CROSSFEED CLOSED. BURN +TOTAL CORRECT.  T/S FOR WING TO WING TXFER COULD NOT DUPLICATE BUT DID FIND LT WING OUTER TANK VENT FLOAT WORN OUT CAUSING TXFER FROM OUTER TO INNER TXFER AT APPROX 200LB PER HOUR REPLACED LT WING VENT FLOAT VLV 15QM REF AMM.  NO LEAKS, OP CHECK OKAY.
