    No. You will need to re-use it. All that you need to do is remove the the air intake tube and disconnect the the wire couplers that go into the WIF sensor to the bottom of the filter.

    Why?


    You can get right to it. The WIF sensor will either be so tight you'll ruin it getting it out or it will come right out. There is a special socket for it that of all things is made of plastic and if they're really tight it just jumps off anyway so what works best is a pair of channel locks, parrot bills, water pump pliers, whatever you want to call them. Just be careful with it. Also apply a light film of vasiline to the orings and it will go back on a little easier. Also make sure the oring seal type hodis in the center of the filter comes off with the old filter. If it stays on the housing make sure you take it off so your not fighting it going back on. Then once the filter is on, open the bleeder a few rounds and pump it up until fuel comes out and then close the bleeder and just barely snug it. Afterall its just plastic and you can't get the bleeder if you break it, you get the whole fuel filter housing.

    Be careful with channel locks, it can be easy to tear up the plastic threads with those. Also, make sure you get that old o-ring off the center, after removing the old one. I learned that the hard way once. KennedyDiesel makes a real nice tool for this, a blue annodized aluminum to remove the WIF sensor.

    x2 on the o-ring, took me a half hour of swearing and sweating trying to get the new filter on before i realized the old one was still stuck to the housing, they dont seem to fit too well with 2 orings for some reason...

    You don't need to remove the intake tube if you are going from the top. There is just enough room to pull the filter up through the top. Just be careful not to drop it once its loose.

    Re: 2006 Duramax fuel filter?

    im doing this same thing, just got a filter and noticed it has a hole in the bottom with threads, i thought that is where the bleeder would be but i havent really looked into it yet(its dark and cold out). so im just wondering if thats where you are talking about the WIF plugging into or not. thanks

    Yes, the WIF sensor screws into the bottom. Bleeder is on bulk head, black screw next to the push primer.

    Honestly, mine seems to run a little better when I put a new filter on. I don't have DIC, but I usually change by 7-10k miles, unless I start popping 1093 codes under hard acceleration. I'm going to do a new one this weekend. FWIW, I carry a spare one behind the backseat as well. Never know when you are going to get some crud in the fuel on the road and need one. Cheap insurance. I also recommend keeping a pair of gloves, changing those things can be messy.
    I unplug the WIF sensor (leaving it screwed into the filter) and then swap it over the new filter after I get the old one out. Also, watch the rubber ring/gaskets, as sometimes they stick to the bulkhead when removing the old filter, and it can be a sumbitch to try to screw that filter back on with both the old ring still on there and the new one in the new filter. I learned that the hardway on a mid-90's day with about 95% humidity.

    How often do you need to replace the fuel filter?

    Did mine this weekend, looked pretty good inside, (I have a Huge aux filter on my lift pumps back by the tank) But I swear it was running a little smoother (and quicker) after the change.
