1990 Ford F250F250

THIS IS NOT A SAFETY RECALL IN ACCORDANCE WITH THE SAFETY ACT. HOWEVER, IT IS DEEMED A SAFETY IMPROVEMENT CAMPAIGN BY THE AGENCY. VEHICLE DESCRIPTION: 1990-1993 FORD F-SERIES VEHICLES EQUIPPED WITH DUAL FUEL TANKS AND 4.9, 5.0,5.8, OR 7.5 LITER GASOLINE FUELED ENGINES. SOME VEHICLES CAN EXPERIENCE A CROSS TANK FUEL FLOW CONDITION DUE TO A DAMAGED CHECK VALVE IN THE FUEL PUMP/SENDER ASSEMBLY. FUEL MAY BE SUPPLIED FROM ONE TANK AND SOME OR ALL OF THE UNUSED FUEL MAY BE RETURNED TO THE OTHER TANK.

UNDER CERTAIN CONDITIONS, THE SNAP RING THAT LOCATES THE PARK GEAR ON THE OUTPUT SHAFT OF THE TRANSMISSION MAY FRACTURE.

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.

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.

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.

INCORRECTLY INSTALLED FUEL LINE CONNECTORS HAVE FUEL SUPPLY AND RETURN LINES CROSSED.
