At PDC by Date in Owner Letter 0% of Parts Direct Shipped to Dealers TO: All Ford Dealers SUBJECT: 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 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. 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.

SEE KIT APPLICATION LIST - SELECT KIT CAREFULLY! KIT APPLICATION (See detailed instructions included in each kit) Owner Letter Serial Number: 12345678901234567 93S68 Kit AA September, 1993 Mr. John Sample 123 Main Street Anywhere, USA 12345 This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Ford Motor Company has determined that a defect which relates to motor vehicle safety exists in 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. SAFETY DEFECT The dual fuel tanks have fuel delivery modules designed to direct fuel to the engine from one tank and to return unused fuel to the same tank. It is possible that one or both fuel delivery modules on your truck could allow a portion of the unused fuel to be directed to the tank other than from which it was drawn.
1990 Ford Truck F 150 2WD Pickup V8-302 5.0L Copyright 2013, ALLDATA 10.52SS Page 5 Should this occur when one tank is at or near full capacity, fuel could overflow from the filler pipe past the 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. REPAIRS At no charge to you, your dealer will replace the fuel pressure regulator and install the check valves. Dealers currently have instructions and parts or parts ordering information. HOW LONG WILL IT TAKE? The time needed for this service is about three hours. However, due to service scheduling times, your dealer may need your vehicle for one full working day. CALL YOUR DEALER Call your dealer without delay. Ask for a service date and whether parts are in stock. When calling, be prepared to tell the dealer the two letter parts kit code printed at the top of this letter (for example, "Kit AA"). If your dealer does not have the parts in stock, they can be ordered before scheduling your service date. Parts would be expected to arrive within a week. When you bring your truck in, give the dealer this letter. If you misplace this letter, your dealer will still do the work, free of charge. CHANGED ADDRESS OR SOLD THE TRUCK? Please fill out the enclosed prepaid postcard and mail it to us if you have changed your address or sold the truck.

PARTS PRICES AND APPLICATIONS FOR KITS JJ AND KK: LABOR ALLOWANCES FOR KITS JJ AND KK: Note - Add 0.1 hour Administrative Allowance to the total repair time. - Add additional 0.1 Hour if truck is over 8,500 lbs. GVWR and equipped with a 5.8L engine. Section III SECTION III - RECALL 93S68 HELPFUL HINTS 1. Always be certain you have the correct kit. Each kit is different and has specific vehicle applications. DO NOT MIX COMPONENTS FROM DIFFERENT KITS. 2. Kits AA, CC, and JJ may contain a new design fuel pressure regulator gasket which appears to have 1/3 of the end cut off. This is normal. 3. When disconnecting Aeroquip fuel line connectors on 1992/1993 models (Kits CC and DD), it may be difficult to completely disengage the locking clip in the connector unless the connector is first pushed onto the male end of the line as far as possible. 4. If the locking clip in the Aeroquip fuel line connector is damaged in the removal of a 1992/1993 fuel line assembly, a new locking clip (basic part number 9B307) must be installed in the connector. Do not attempt to repair the damaged locking clip. 5. When servicing the aft-axle tank on the 1990/1991 models (Kits AA and BB), reinstallation of the fuel line after the check valve is installed on the supply side of the fuel delivery module may be difficult due to limited clearance to the crossmember. Installation may be easier if the installation sequence defined in the kit instructions for the aft-axle tank is reversed and the check valve is connected to the fuel line BEFORE attaching to the fuel delivery module. If necessary, the fuel line hold-down clip on the crossmember may be temporarily opened to allow the end of the supply line to be moved to the forward side of the crossmember for easier access. Reinstall all lines in the clip when completed. 6. If a plastic elbow connector is damaged on a 1990/1991 fuel line assembly, the line can be repaired by either of two methods: a) The damaged connector may be cut off and a replacement connector (part number N806797-S19O) installed using Rotunda Tool 134-00001. OR b) the damaged connector and a section of fuel line may be cut off and a new section of fuel line including a connector (basic part number 9291) may be spliced onto the existing fuel line using Rotunda Tool 134-000001. Use connector N806119-S to perform the splice. Trim the lines to the desired length before splicing.
1990 Ford Truck F 150 2WD Pickup V8-302 5.0L Copyright 2013, ALLDATA 10.52SS Page 10 7. Special precautions must be taken to prevent kinked fuel lines as pointed out in the kit instructions. BE SURE TO READ AND FAMILIARIZE YOURSELF WITH THESE PRECAUTIONS. For additional information, Technical Service Bulletin 91-23-10 also addresses the issue of kinked fuel lines. 8. When reinstalling fuel lines after installation of the check valve connector from the kit, be sure that BOTH safety clips are properly reinstalled (one clip between check valve connector and the fuel delivery module; second clip between the fuel supply line and the check valve connector). 9. In the event that a fuel line is inadvertently damaged during kit installation, repair using parts, tools, and procedures found under Group 10 in the appropriate Shop Manual and Technical Service Bulletin 92-12-16.
