## Discrepancy

(CAN) DURING THE WALK AROUND THE PILOT NOTICED FUEL LEAKING FROM ONE OF THE PANELS UNDER THE AIRCRAFT.  MAINTENANCE WAS NOTIFIED AND INVESTIGATION REVEALED THAT THE ELECTRIC FUEL BOOST PUMP WAS LEAKING FROM THE PRESSURE REGULATOR ADJUSTMENT.  PUMP WAS REPLACE WITH A SERVICEABLE UNIT AND THE AIRCRAFT RETURNED TO SERVICE. THE PUMP IN QUESTION HAD RECENTLY BEEN OVERHAULED AND HAD ONLY BEEN IN OPERATION FOR 28.1 HOURS.
