Where is my fuel filter located on 2002 Ford Explorer Sport Trac

Where is my fuel filter located? Is this something that can be done at home or best done at a shop-and why?

The fuel filter is at the rear of the vehicle inside and attached to the chassis leg I think drivers side. The filter is easy to change but needs a "disconnect tool" that slips along the fuel line to release the plastic clips that keep the fuel lines in the fuel filter. The tool is cheap and available in any autoparts store.
