## Discrepancy

FUEL DRAINED FROM ONE SIDE TO OTHER CAUSING LOW TANK TO FLOOD.  UNABLE TO MOVE FUEL SELECTORS TO OFF POSITION.  REMOVED SELECTOR AND FOUND BOTH LEFT AND RIGHT SELECTOR O-RINGS IN A MELTED STATE, PARTS OF O-RINGS IN SELECT OR RACK GEAR.  ONE SET OF O-RINGS HAVE DISINTEGRATED.  APPEARS THE LACK OF USE AND TIME WERE A CONTRIBUTING FACTOR.  (REFERENCE AD 80-18-10 AND PIPER SB 648A.  (THESE ARE ON A PA31).  THE VALVE IS SIMILAR AND THE PROBLEM THE SAME).
