## Discrepancy

OWNER STATED ONE VALVE WOULD NOT OPEN AND A 'GREENISH STICKY' SUBSTANCE WAS FOU ND IN THE OTHER.  REPLACED BOTH WING TANK DRAIN VALVES.  CHECKED AND CLEANED ALL FUEL SYSTEM SCREENS AND FILTERS.  NO DEFECTS NOTED.  DRAINED 5 GALLONS FROM EACH TANK, NO DEBRIS NOTED.  EXAMINED VALVES, O-RINGS APPEARED TO HAVE DETERIORATED.  ALSO, POSSIBLE THAT SEALING COMPOUND FROM BLADDERS MAY HAVE BEEN THE CAUSE.  BOTH BLADDERS WERE REPLACED RECENTLY (1 NEW, 1 REBUILT).
