AFTER REPLACING A NAVIGATION LIGHT BULB, MX WENT INTO THE COCKPIT TO TURN ON THE SWITCH TO TEST IT AND SMELLED A FAIRLY STRONG FUEL SMELL. AFTER FURTHER EXAMINATION, THE RT FUEL LINE FROM THE RT AFT TANK OUTLET TO THE "T" UNDER THE FLOOR HAD A PINHOLE IN THE LINE JUST UNDER THE RT DOOR MOST LIKELY FROM CORROSION. THE LINE WAS REPLACED AND LEAK CHECKED SERVICEABLE.
