ATTACHMENT I: Owner Letter
-----------------------------------------------------------------------------------
At Ford Motor Company, we are constantly working to improve our products. The reason for this letter is to tell you about a no charge coverage program (Extended Coverage Program 01M05).

What is the no charge coverage program? Your vehicle may experience a fuel cross-flow condition if the check valve in the fuel pump/sender assembly becomes damaged. If this check valve becomes damaged, fuel may be supplied from one tank and some or all of the unused fuel may be returned to the other tank. Should this occur, the capacity of the receiving tank may be exceeded and fuel may overflow from the filler cap.Note: Your vehicle was covered under Safety Recall 93S68 which was initiated in late 1993 to address fuel cross-flow. If Safety Recall 93S68 has never been performed on your vehicle, we encourage you to have it performed. If Safety Recall 93S68 was performed and you are still experiencing fuel cross-flow, then the cost to repair the cross-flow condition will be covered under this extended coverage program, number 01M05.

Note: Your vehicle was covered under Safety Recall 93S68 which was initiated in late 1993 to address fuel cross-flow. If Safety Recall 93S68 has never been performed on your vehicle, we encourage you to have it performed. If Safety Recall 93S68 was performed and you are still experiencing fuel cross-flow, then the cost to repair the cross-flow condition will be covered under this extended coverage program, number 01M05.

What does Extended Coverage Program 01M05 cover?... This program extends the coverage for the cross-flow condition to 12 years or 150,000 miles from your vehicle's warranty start date, whichever occurs first. This coverage will automatically transfer to subsequent owners. If the vehicle already has more than 150,000 miles, this coverage will last until December 31, 2001.

If your vehicle should experience a fuel cross-flow condition, your dealership will repair the condition free of charge (parts and labor).

Safety Recall 93S68 - All 1990, 1991, 1992 and certain 1993 Model Year F-Series Vehicles equipped with 4.9, 5.0, 5.8 or 7.5 Liter Engines and Dual Fuel Tanks

Affected Vehicles
All 1990, 1991, 1992 and certain 1993 model F-Series vehicles equipped with 4.9, 5.0, 5.8 or 7.5 Liter engines and dual fuel tanks.

Reasons For Recall
Some of the affected vehicles may experience a cross tank fuel flow condition due to the 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. Should this occur, the capacity of the receiving tank may be exceeded and fuel may overflow from the filler cap. Fuel spillage in the presence of an ignition source could potentially result in a fire.

To correct this condition, the fuel pressure regulator will be replaced and a check valve will be installed between each fuel supply line and fuel tank.

Free Fuel Line Removal Tool
Standard fuel line removal tools can be used to disconnect fuel lines. However, because of the number of vehicles to be serviced, two free tools (#T93T-9550-AH) will be provided to each Ford dealer. These tools will be in your next Dealer Mail System (DMS) shipment (DMS packing slip #930902).

Parts Kit Codes
The required parts kit code for each vehicle will be shown on the attached VIN listing and will be printed at the top of each Owner Letter. Ask owners for the kit code shown on their letter when the owner calls for a service appointment.

Affected Vehicles: 1990 - 1992 and certain 1993 Model Year F-Series vehicles with 4.9, 5.0, 5.8 or 7.5 Liter Engines and Dual Fuel Tanks

WARNING: DO NOT SMOKE, CARRY LIGHTED TOBACCO OR ANY OPEN FLAME OF ANY TYPE WHEN WORKING ON OR NEAR ANY FUEL-RELATED COMPONENT. HIGHLY FLAMMABLE MIXTURES ARE ALWAYS PRESENT AND MAY BE IGNITED, RESULTING IN POSSIBLE PERSONAL INJURY.

Safety Recall 00S57 - Certain 1993 Model Year F-Series Vehicles Equipped with Dual Fuel Tanks and 4.9, 5.0, 5.8 or 7.5 Liter Engines - Fuel Pressure Regulator

AFFECTED VEHICLES

The following 1993 model year Ford F-Series Trucks equipped with dual fuel tanks and 4.9, 5.0, 5.8 or 7.5 Liter engines produced at the following assembly plants:

Kansas City Assembly Plant from November 13, 1992 through August 21, 1993
Michigan Truck plant from November 23, 1992 through August 13, 1993
Norfolk Assembly Plant from November 12, 1992 through August 2, 1993
Chassis Cab vehicles built at Ontario Assembly Plant from November 11, 1992 through August 24, 1993
SAFETY CONCERN

The affected vehicles have a carbon steel fuel pressure regulator in the fuel system that may wear out during the life of the vehicle. If this should occur, the vehicle may experience a cross tank fuel flow condition. Fuel may be supplied from one tank and some or all of the unused fuel may be returned to the other tank. Should this occur, the capacity of the receiving tank may be exceeded and fuel may overflow from the filler cap. Fuel spillage in the presence of an ignition source could potentially result in a fire.

SERVICE ACTION

To correct this condition, the fuel pressure regulator will be replaced on all affected vehicles.

OTHER COVERAGE

All of the vehicles affected by Safety Recall 00S57 (Fuel Pressure Regulator Replacement) are also affected by Owner Notification Program 01M05 (extended coverage for the cross-flow condition). For this reason, 00S57 is being launched concurrently with Owner Notification Program 01M05. If an affected customer reports fuel cross-flow, always complete Safety Recall 00S57 first and release the vehicle. Program 01M05 only applies if the customer reports fuel cross-flow after Safety Recall 00S57 has been completed.

Safety Recall 00S57: To eliminate fuel cross-flow between fuel tanks, your dealer will install a revised stainless steel fuel pressure regulator. This service will be performed on your vehicle free of charge (parts and labor).
Extended Coverage Program 01M05: This program extends the coverage for the potential fuel cross-flow condition to 12 years or 150,000 miles from your vehicle's warranty start date, whichever occurs first. This coverage will automatically transfer to subsequent owners. If the vehicle already has more than 150,000 miles, this coverage will last until December 31, 2001.

Technical Information
For replacement of the Fuel Pressure Regulator, please follow the procedures in the appropriate Workshop Manual.
