What was found
FUEL CONFIGURATION LIGHT ILLUMINATED. SUPPLEMENTAL DATA UPDATE THE CAUSE WAS A COMBINATION OF A LEAK IN THE RIGHT ENGINE DRY BAY AND A DEFECTIVE RIGHT MAIN TANK FUEL FILL VALVE CONTROL UNIT. THE PRIMARY CAUSE OF IMBALANCE CAN BE ATTRIBUTED TO THE FUEL FILL VALVE CONTROL UNIT WHICH WAS STUCK IN THE OPEN POSITION. AN OPEN FUEL FILL VALVE CONTROL UNIT TOGETHER WITH A FULL LOAD OF FUEL IN A CLIMB WOULD TRANSFER FUEL BACK INTO THE FUELING MANIFOLD WHERE IT WOULD DRAIN INTO THE CENTER TANK.
