How do i change the fuel filter on a 2002 Mountaineer AWD 4.0L?

I've located the filter on the passenger side frame rail in front of the fuel tank and behind a plastic shroud. Is there some sort of special tool I need to remove the lines and is there a need to disconnect the computer and/or battery?How do i change the fuel filter on a 2002 Mountaineer AWD 4.0L?
Yes, you need a special tool. They can be bought at your local auto parts store and are specifically for Ford car and truck fuel line connections. The tool slips over the line, and you push it into the end of the connection. the tool stretches the spring inside the line connection and allows you to remove the line. No need to disconnect the battery/
