The fuel system in Ford’s 2001 model year Explorer Sport Trac is equipped with a fuel filter, which catches debris and foreign material present in the gas before it reaches and clogs the fuel injectors. To maintain the fuel system–which affects the vehicle’s exhaust emission levels–replace the fuel filter in your Sport Trac every 30,000 miles.
Tools Used: Tools, Wrench set, Fuel pressure gauge (Ford part number T80L-9974-B or equivalent), Gas can
Change a Fuel Filter: Open the hood. Use a wrench to disconnect the battery’s negative cable. Locate the Schrader valve on the fuel rail. The Schrader valve has a nipple on it that looks like a tire valve stem. Remove the Schrader valve’s cap. Attach the fuel pressure gauge to the Schrader valve, then open the manual valve on the gauge slowly. If gasoline drains as pressure is released, collect the gas in the gas can. Unclip the safety clips from the hoses on either side of the fuel filter. Grasp, twist slightly, then remove the hoses from the filter. Remove the fuel filter from the support bracket. Install the new filter in the support bracket. Reverse the dis-assembly procedure to install the new filter.
Tips & Warnings: Gasoline is a highly flammable mixture. Sparks or open flame can ignite gas fumes, resulting in property damage and personal injury.
