1991 Ford F250 Pickup 4WD

A REVISED BRAKE LINING NOISE INSULATOR RESULTED IN A DECREASE IN THE THERMAL INSULATION BETWEEN THE BRAKE LINING AND THE FRONT BRAKE CALIPER PISTON. THIS CAUSED GREATER HEAT TRANSFER TO THE CALIPER PISTONS WITH THE POTENTIAL TO OVERHEAT THE BRAKE FLUID AND DIMINISH BRAKE EFFECTIVENESS DURING SEVERE BRAKING CONDITIONS.

A MALFUNCTIONING CHECK VALVE WITHIN THE FUEL PUMP ASSEMBLY CAUSES A PORTION OF THE UNUSED FUEL FROM ONE TANK TO BE RETURNED TO THE SECOND TANK. WHEN THIS OCCURS, THE CAPACITY OF THE SECOND TANK CAN BE EXCEEDED, CAUSING FUEL SPILLAGE.

KEYS ATTACHED TO THE KEY RING OF AN IGNITION KEY WHILE IT IS IN THE VEHICLE IGNITION CAN BECOME LODGED IN THE STEERING LOCK RECEIVER AS THE STEERING WHEEL IS BEING TURNED.

THE STEEL FUEL RETURN TUBES THAT CONNECT THE FRAME FUEL RETURN LINES WITH THE ENGINE FUEL RAIL CAN CONTACT THE PINCH WELD FLANGE CONNECTING THE DASH PANEL TO THE FLOOR PAN. CONTINUED CONTACT LEADS TO ABRASION OF THE STEEL FUEL RETURN TUBE AND EVENTUALLY RESULTS IN A FUEL LEAK.

THE IGNITION SWITCH COULD EXPERIENCE AN INTERNAL SHORT CIRCUIT.
