This one can be a real " fun" job to do. The filter is located under the truck on the driver's side along the inside side of the frame. It is cylinder shaped with a metal fuel line connected at each end. You will need a 5/8" wrench and a 13/16" wrench, and some Liquid Wrench (penetrating oil), or similar product, and a new fuel filter.
1. Locate the fuel filter on your truck.
2. Spray the ends of the fuel filter and line fittings, where the lines connect into the fuel filter, with the Liquid Wrench .
3. Wait about two hours for the oil (Liquid Wrench ) to soak into the fittings, and break the rust loose.
4. Loosen the fittings on each end. (5/8" wrench on the fuel line side and 13/16" on the filter side)
NOTE: it is important to loosen each connection individually to avoid twisting and damaging any of the fuel lines.
5. Remove the filter from the plastic retaining clip
6. Cycle the key on and off once to pump any contaminants out of the fuel line.
7. Install the new filter into the plastic retaining clip noting the direction of flow. The " in" end of the filter should be placed toward the rear of the vehicle, and the " out" end toward the front.
8. Attach the fuel line fittings to the new filter.
9. Start the vehicle, and check for leaks.
If you have too much trouble getting the truck to start after you replace the filter use some starting fluid to get the truck to run enough to get the air out of the fuel system.
