## Discrepancy

(CAN) DURING FLIGHT, THE PILOT NOTICED THE NR 2 ENGINE FUEL GAUGE DROPPING RAPIDLY WITH A CORRESPONDING DROP IN FUEL PRESSURE. THE EMERGENCY FUEL PUMP WAS SELECTED ON AND THE FUEL LOSS INCREASED. THE ENGINE COUGHED AND THE FUEL CROSS FEED WAS SELECTED, STILL FUEL WAS LOST. THE AIRCRAFT LANDED AND POST FLIGHT INSPECITON FOUND THE FUEL PUMP SEAL OR THE PUMP INTERNAL DIAPHRAGM HAD FAILED. THE FUEL PUMP WAS REPLACED.
