## Discrepancy

(CAN) WHILE PERFORMING POST FLIGHT DAILY INSPECTION , TURNED ON BOOSTER PUMP AND NOTICED FUEL LEAKING FROM ENGINE DRAIN.  FOLLOWED LEAK TO SEAL DRAIN OF HIGH PRESSURE ENGINE FUEL PUMP.  WHEN BOOST PUMP TURNED (OFF) LEAK STOPPED.  LEAK WAS PRODUCING 6 ML PER MINUTE.   DID NOT SUSPECT HP PUMP WAS LEAKING FUEL IN FLIGHT AS NO FUEL DISCOVERED ON TARMAC AFTER AIRCRAFT LANDED AND NO FUEL RESIDUE ON SIDE OF FUSELAGE OR TAILBOOM.  PUMP SEAL WILL BE REPLACED ONCE PARTS ARE RECEIVED.
