POSITION) BUT FUEL WAS NEVER TRANSFERRED TO THE INNER TANK TILL FINAL AT 20 00 FEET. THE LEFT TRANSFERRED NORMALLY. THE AIRCRAFT LANDED SAFELY AT PHL WITHOUT FURTHER INCIDENT. MAINTENANCE REPORTED THAT PREVIOUS LEGS HAD MULTIPLE FAULTS FOR THE FUEL LEVEL SENSING CONTROL UNIT (9QJ) MAINTENANCE REPLACED THE FUEL LEVEL SENSING CONTROL UNIT (9QJ) AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK PER AMM 28-46-34.
