Wj Fuel Filter - Once and For All

(FYI, I'm talking about the external fuel filter/regulator, not the in-tank filter)

Ok, I've read as many fuel filter threads on here as I could find and I know that wjjeeps (or Chrysler, rather) says you should only replace the fuel filter as needed or once there is a problem. I've seen plenty of people on here who seem to disagree with that notion stating that if a filter is good for the life of a vehicle, it must not be doing a very good job filtering.

So what's your opinion? Do what the manufacturer says and wait till you have a problem before replacing the filter, or do you replace on some kind of regular maintenance schedule?

If you think it should be done on a regular basis, please indicate what kind of interval you think is best.

I have been thinking about changing mine. Have close to 111,000 miles. They are expensive though. So I would think since people are driving these things well past 100,000 miles that at 100,000 it may be a good idea to change it.

I just picked a WIX up for $35 at my local Baxter Auto Parts. Not that bad of a price. I will change it tonight and be driving 300 miles north tomorrow so I will see what happens. Oh yeah and I have almost 50K on mine.

I attempted the removal and install but could not get all the little hoses off. I might just take it to a shop and have them do it.

Oh come on... It takes a little time. Don't wuss out. Look this over and try again. The one that is all metal, I used a 7/16 inch open ended wrench to push in the clip and then once its in pull the hose off.

I just did this job myself -- it is a REAL PIA no doubt. Don't be discouraged though -- they are actually easy if you know what to do. Ok, there's 3 hoses right? Two on the left and one on the right. Well to get the 2 off with the white plastic clips, you have to insert a round sleeve in between the junction to spread the clip tabs and the lines will come apart. Since this is nearly impossible to do, don't waste your time, instead cut the filter off with a pair of dykes as close to the filter housing as possible, leaving yourself as much protruding line as possible. Then, take two little screwdrivers (or a fuel line removal tool if you can find one, occasionally they're included with the filter) and stick them up in between the line/hose. Pop the two tabs of the white plastic clip. Use a pair of pliers or vice grips to pull the old filter line out. The third hose was the trickiest for me -- I didn't realize until a mechanic walked over and did it in 2 seconds that you actually squeeze the black part of the line, and pull the line straight out -- you still have to release from the white clip inside the hose but it's not even necessary to save this one. Be very careful though, would hate to have to change those hoses JC. Smoking recommended.
