## Discrepancy

DIVERTED TO BNA DUE TO THE FLIGHT CREW REPORTING THAT FUEL APPEARED NOT TO BE BURNING OUT OF THE LEFT WING TANK. MAINTENANCE VERIFIED THAT THE CROSS-FEEDS AND DEFUEL VALVES WERE OPERATING NORMALLY. THE LEFT TANK FUEL BOOST PUMP OPERATION CHECKED GOOD. A HIGH POWER ENGINE RUN WAS PERFORMED. MAINTENANCE WAS UNABLE TO DUPLICATE THE FAULT.  THE CHECK VALVE FLUSH PROCEDURE WAS PERFORMED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
