Depressurizing Fuel system
 
OK. The standard way is to yank that huge fuse, and wait for the car to stall out, then release pressure from the gas tank cap.

Anyways, that damn fuse. What is the best way to pull it. I was doing this when I installed my fuel pressure sensor, I couldn't get crap for purchase on it and ended up cracking the side open. For paranoias sake I got a new one from the dealer and got sodomized on the price ~$70.

So what is the best way to pull it? I deally I think I want something like a CPU puller, that has little perpendicular tines that can slip under it to pull it up, but my CPU puller wouldn't do the job

Flat-head screwdriver, and pry it up gently?

All I can think of is either that or a small pair of pliers if you can find a pair that fits over the fuse and between everything else.

I can try that, but as I recall, it isn't as if you come straight in from the side with clear access to the bottom.

I'm thinking I need to get off my ass and change the fuel filter, I already have the part, but I been putting off that pain in the ass job (~25K on the car).

I just used a pair of needle-nose pliers, and carefully pulled it up, IIRC.

about to go do the fuel filter now on jack stands, heard that it was just annoying, not hard but time consuming. Wish me luck...

I'm not sure what they are called but i use a larger pair of pliers that can adjust so that the grasps are about the same size as the relay and they i grasp the smaller sides(guessing more strength do to less area) and i gentally rock them out. Most the time this works but i think your always at risk of cracking them. But I have used one that had a crack in the side, one where the top cracked off, and one were the cover was completly gone and i've had no isses.

a/k/a vise grips?

channel locks maybe? Mine came out by hand but damn it was a bitch.

I dont know if I recommend my technique to depressurize but if you want to use it....

I loosen the nut on the front of the secondary rail with a socket while holding a towel around it. Some gas does come out but it's not as much as you'd think.

I will make the disclaimer that it has been a longtime since my fuel system was stock but I am 99% sure that is what I did back then.

There is a fuse under the dash that will cut the fuel pump. IIRC it is a 10 amp fuse.

I always just remove the filler cap to release pressure, then replace the filter. I've never had a problem other than the normal amount of fuel you get running down to your armpit. :D

a good 1/4 inch drive extension and a 10mm wobble are you best friends when doing the fuel filter.

craftsman robo grip pulls the fuse nicely, you can also unplug the fuel pump resistor under your brake booster (much easier)

I wish I had looked up this thread again. I ended up cracking freaking fuel relay #2. Screw it. Electrical tape over it and I'll roll with that. I still have the old one with electrical tape. The dealer can blow me if they want $70 for one again.
