What was found
(CAN) FUEL QUANTITY INDICATION WOULD STICK AT APPROXIMATELY 60-65 GALLONS WHEN TANK IS FULL. REMOVAL OF THE LOWER QUANTITY TRANSMITTER REVEALED A BROKEN SOLDER JOINT ALLOWING THE FLOAT TO TWIST APPROXIMATELY 45 DEGREES WHICH ALLOWED FLOAT TO JAM WHILE CONTACTING AN INTERNAL FUEL CELL LINE.
