My 2005 Jeep Liberty Limited 4x4 CRD has 17,623 miles on the clock as of today and it's time for its 3rd oil change (I've been on about a 5700 to 6000 mile drain interval or so).
The fuel filter has a recommended replacement interval of 25k miles, but I really don't want to stretch it that far.
I recently purchased the fuel filter from Cornett Chrysler in Irvine, KY.....part number 52129238AA........lists for $44.22 and my cost was $27.50 plus tax.
Here's a few pics of the filter.
This is the bottom part of the fuel filter.
If you look in the previous picture, you'll see a white "dummy" plastic plug that threads into the bottom of the fuel filter.....this is where the water is regularly drained from the fuel filter and where the WIF (Water In Fuel) sensor is located.
This is the top part of the fuel filter.
There's two o-rings / gaskets that need a light coating of diesel and / or diesel fuel supplement applied to them prior to installation.
Note the white filter media through the six holes in the filter.
If you look a tad harder, you'll see the bottom of the filter where the WIF Sensor is attached.
Fuel Delivery Diagram 2.8L CRD.
You'll need a good set of car / truck ramps to pull the front end on.....the fuel filter change will have to be done from the bottom.
Start off by disconnecting the water in fuel sensor located at the bottom of the filter. Do not unscrew the WIF sensor yet, unless you want some nice #2 running down your arm into your armpit. Simply feel your way around the connector, and then simply squeeze and pull the connector at the same time.
You'll need either a home-made strap type wrench or a fluted oil filter wrench to loosen the fuel filter. Unscrew it counter clockwise and ease it down with care. Due to clearance issues, I'll be buying an appropriate fluted oil filter wrench in the near future.
After removing the filter, clean the fuel filter housing with a clean paper towel. Ensure that both the center (small) o-ring and large o-ring are on the old filter and not the housing to prevent a double-gasketing scenario. This is easier performed from the top, underhood.
Transfer the WIF sensor from the old filter onto the new one. If you kept the filter in its original vertical position, you can see how loosening the WIF sensor also doubles as the drain for routine draining.
Prime the new fuel filter with your choice of diesel fuel supplement (I used Power Service as it's readily available). Be patient as you fill it up....the more you get into the filter, the less pushing of the priming button you'll have to do for a re-start. Coat both o-rings (large and small) with diesel fuel supplement.
Thread onto the housing and tighten by hand. Reconnect the WIF sensor connector. You'll need a 1/2" wrench to open the air bleed screw....open it up two or three turns. Place a shop towel near the nipple end of the air bleed screw and hit the primer button until you see all diesel and no air coming out......usually not much more than 6 to 8 pumps if you primed the filter with diesel fuel supplement right the first time.
Tighten air bleed screw.....start up, and check for leaks.
Piece of cake....unless you have huge arms.....it's a little tight getting to everything from below.
Sorry for the lack of pictures regarding the fuel filter change itself.....I was also performing an oil & filter change and tire rotation, and my hands were rotten from the work......didn't want to trash the ol' digital camera.
