Fuel Filter
Well, I've started a tune up on my 94' 4x4 with the I-6. I've replaced the spark plugs, wires, distributor cap, and rotary button. I'm putting a K&N air filter in it later this week. I'm going to replace the fuel filter soon, but don't know what I'm doing really.
How do I need to decompress the fuel lines. I've read somewhere about letting the truck run and pulling a fuse until is shuts off or something about a decompression switch somewhere. Which one should I do? Also what kind of tool am I going to need to get the line off the filter. I don't see any kind of clamp like I've read about. I'm not real mechanically inclined, but I'm working on it! Thanks I'll post some pics of the truck soon.

Its fairly easy to change without tools, I would relieve the pressure at the fuel rail. Theres a small thing that looks like a valve stem for a tire. Take a small screwdriver and push in the center while watchin for spray in ur face. Once u get no pressure climb under and pull loose the clamp that holds the filter in place. I use a small screwdriver to release the clips and then it just slides out. U will get stinky like gas doing this but its not too hard

Do not use a screwdriver to pry the fittings off the ends of the filter. You will need a tool like this. A'zone, Orielly, or Advance etc should have it.

The easiest way to depressurize the fuel system is to remove the fuel pump relay and try to start the truck. It will sputter and die, then crank it for a couple of seconds and that should take care of the fuel pressure. That way you don't have to worry about spraying fuel by relieving the pressure at the test port.

I dont pry apart the filter i pry out the clip, its one side has teeth so i pull out the non toothed part first then carefully press in on the toothed side. I have plenty of pratice doing it this way and dont even break the clip
