## Discrepancy

PILOTS STATED FUEL INDICATION WAS SOME TIMES UNRELIABLE.  REMOVED FUEL INDICATOR PANEL AND FOUND CORROSION ON BRACKET THAT SERVES AS MOUNT FOR FUEL INDICATOR DIODES.  SUSPECT THAT CORROSION ALLOWED A GROUND TO DIODES.  (DIODES ARE NORMALLY INSULATED FROM BRACKET). THIS BRACKET IS DIRECTLY UNDER THE PILOTS VENT WINDOW.  SUSPECT MOISTURE FROM LEAKING WINDOW SEAL CAUSED CORROSION.  CORROSION WAS CLEANED FROM BRACKET.  NEW INSULATORS INSTALLED.  SYSTEM FUNCTIONS NORMALLY.
