- 1). Locate the fuel-pump inertia switch under the passenger's side of the dash in your Explorer. Disconnect the electrical connector from the switch and lay it aside. Crank the engine for 20 to 30 seconds or if it starts, let it run out of fuel. This will depressurize the lines.
- 2). Locate the fuel filter under the driver's side frame of the truck. The filter is about half way back on the frame.
- 3). Locate the two retaining nuts on the bottom of the frame and threaded onto the mounting studs of the fuel-filter mounting bracket. Using a wrench, turn the nuts counterclockwise, removing them from the studs.
- 4). Pull the bracket out of the frame and locate the hose clamp that holds the bracket to the filter. Remove the clamp with a flat screwdriver, separate the bracket, and filter. You now have better access to the fuel-line fittings at each end of the filter.
- 5). Locate the first connector on the fuel line at the front of the filter. A hairpin connector runs through the push-on section of the fitting. Spread the two ends of the hairpin connector about 1/8-inch apart and pull the hairpin piece out of the fitting. The front line is now free. Repeat this step on the rear line.
- 6). Remove the fuel filter from under the truck and discard it.
