What was found
PILOT REPORTED ON PRE-FLIGHT, FUEL WAS DRIPPING FROM THE RIGHT WING NACELLE BEHIND THE ENGINE. UPON INSPECTION, THE FUEL OUTLET NIPPLE HAD A SMALL HOLE. POSSIBLE CAUSE WAS MAIN FUEL LINE IS NOT SUPPORTED IN THAT AREA AND THE GROMMET USED BY PIPER WAS TOO SMALL WHERE THE FUEL LINE WENT THROUGH A RIB. VIBRATIONS FROM ENGINE POSSIBLY WORKED THE NIPPLE UNTIL IT DEVELOPED A HOLE. FUEL BLADDER WAS REPLACED WITH NEW. (X)
