Recall History (4 recalls)
EQUIPMENT
CERTAIN HONEYWELL FRAM RACING BRAND HP4 AND HP8 OIL FILTERS THAT WERE MANUFACTURED FROM MAY 25, 2006, THROUGH SEPTEMBER 14, 2007, AND SOLD FOR USE AS REPLACEMENT EQUIPMENT FOR VEHICLES LIST ABOVE. THE AFFECTED FILTERS ARE MARKED WITH A DATE CODE A61451 THROUGH A72571 SEQUENTIALLY. THE DATE CODE AND PART NUMBER APPEAR ON THE FILTER HOUSING.

FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
THE PASSENGER COMPARTMENT IS SEPARATED FROM THE ENGINE COMPARTMENT BY AN INSULATED ENGINE COVER. THE INSULATION INSIDE THIS COVER CAN RUB AGAINST THE FUEL RETURN HOSE RESULTING IN A FUEL LEAK. ADDITIONALLY, A WIRING HARNESS CAN ALSO WEAR THROUGH CAUSING INTERRUPTION TO SOME ELECTRICAL OPERATIONS, INCLUDING THE FUEL PUMP.
FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
THE OIL PRESSURE SWITCH WHICH CONTROLS THE POWER TO THE ELECTRIC FUEL PUMP CAN FAIL. FAILURE IS DUE TO A MISSING RUBBER SEAL BETWEEN THE SWITCH AND THE WIRING HARNESS. THE MISSING SEAL ALLOWS CONTAMINANTS TO ENTER THE SWITCH CAUSING IT TO FAIL IN THE OPEN OR CLOSED POSITION.
VEHICLE SPEED CONTROL:ACCELERATOR PEDAL
THE COATING USED TO PROTECT THE ACCELERATOR PEDAL SHAFT IS INCOMPATIBLE WITH THE BRONZE BUSHING THROUGH WHICH THE SHAFT PASSES. OVER TIME, AND IN THE PRESENCE OF A CORROSIVE ENVIRONMENT (WATER, ROAD SALT), THE SHAFT CAN CORRODE INSIDE THE BUSHING INCREASING THE AMOUNT OF FRICTION BETWEEN THE ROTATING SHAFT AND THE STATIONARY BUSHING.
