How do you change a fuel filter on a 2003 Nissan Frontier 4x4?

I will give it a shot at telling you. I did it but it has been a while so I can not remember exactly. It is behind a shield. It sits under the bed about 2 foot from passanger door. It is a cylinder and if you buy the new one you will have an idea of exactly what it looks like. I can not remember having to pull the shield just a nut that holds the fuel filter bracket and the entire filter had enough line to slide out of its hole and drop down to where you can get on the clamps on each side they were spring clamps and I just did them with pliers. I advise clamping the hose on each side especially the side from the tank it has pressure on it. Or be ready to spray some gas when you unhook the hose so watch out for that. Hope this helped
