For a 2003 it is on the frame rail under the drivers side door. Don't bother taking off the black holster that holds the fuel filter onto the frame rail.
1 )Simply unscrew the nuts on both sides of the fuel filter. It will be under pressure. Wear safety goggles. A couple of cups of fuel will spill.
2) Look at the fuel line on the engine side. Notice the clip holding in the line. Remove the line from the clip.
3) Remove the fuel lines from the filter starting with the side toward the engine. This side has more play/laxity in the line.
4) Slide out the fuel filter from the black holster.
5) Slide in the new fuel filter with the flow directional arrow pointing toward the engine.
6) Attach the fuel line to the filter starting with the tank side first. Don't force it and thread out the fittings.
7) Attach the engine side fuel line. The fitting would come together by hand screwing the male into the female end. I did have to use a wrench to gently start it.
Total project time 20-40 min. Change it every 30k.
