Relieve the fuel system pressure. Raise the vehicle and support it securely on jackstands. Place a container, newspapers or rags under the fuel filter. Use two wrenches, one to steady the filter and the other to unscrew the fuel line nut, then separate the connections. Use two wrenches to loosen the fuel lines and detach if from the filter. If available, use a flare nut wrench on the fuel line nut fitting. On 1997 and later models one end of the fuel filter has a quick disconnect fitting-to remove the line squeeze the plastic clips on the fitting together and pull back on the line. It's a good idea to use a flarenut wrench because the wrap-around design gives it a better grip on the fuel line nut. Detach the filter from the bracket. Install the new filter and connect the fuel lines securely.

On 2004 and later models, the fuel filter is an integral part of the fuel pump module and is not serviceable. The fuel filter is mounted under the vehicle, in front of the gas tank. Begin by relieving the fuel system pressure. If necessary, raise the vehicle and support it securely on jackstands. Inspect the fittings at both ends of the filter to ensure they are clean; if more than a light coating of dust is present, clean the fittings before proceeding. Release the clips holding the fuel lines to the filter by squeezing the tabs, then remove the bracket bolt and take out the filter. Detach the fuel hoses one at a time from the filter, being prepared for fuel spillage. After the lines are detached, check the fittings for damage and distortion, and ensure they are reattached to the new filter, using new clips if packaged with it. Remove the fuel filter from the mounting clamp, noting the direction of installation, and install the new filter in the same direction. Carefully push each hose onto the filter until it is seated against the collar on the fitting, then install the clips, ensuring they are securely attached to prevent the hoses from backing off the filter, which could lead to a fire. Finally, start the engine and check for fuel leaks.
