Can we assume then that the WIX 33647 that is specified for the CRD fits the requirement of 2 microns? I did not have any luck tracking down a WIX a year ago. It was a special order item that was not available. According to the WIX web site it should be available now.

I looked at WIX web site and found nothing concerning filtration size:
 
http://www.rockauto.com/dbphp/mfr,WIX,Fuel%252FAir,6200,Fuel+Filter
 
Then "Part Number Search" tab
 

Part Number: 33647
Principal Application: Jeep Liberty w/ 2.8L Common Rail Diesel (05-06) All Applications
Style: Spin-On Fuel/Water Separator Filter
Service: Fuel
Type: Full Flow
Media: Paper
Height: 7.322
Outer Diameter Top: 3.444
Outer Diameter Bottom: Closed
Thread Size: 16X1.5 MM
 
Gasket Diameters:
O.D. 2.770
I.D. 2.440
Thk. 0.240

 
Personally speaking I would not use this cartridge because two main functions will be removed:
- The water in fuel sensing
- The pre-heating of the fuel for winter use.
 
Don't you have a Parker Racor equivalent? Mine is the R20S. It's the clone of the Mopar filter, and Parker once wrote they were doing good business with Chrysler Marine Diesel

I found this code concerning the Grand Cherokee. It could be similar to the Liberty CRD.
 
P0178:
-Water in Fuel Light—Water In Fuel Sensor Voltage Too Low

Cause:
- Loss of water-in-fuel circuit or sensor.

Caribout1.... If you look at the filter the filter is a clone of the mopar filter. The one that don't have the water fuel sensing orifes is the cat175-2949 that lubrication specialist are selling as the replacement for the mopar filter. I am with you for the sensor, but the source said that you do not need that sensor because as soon as the water get in to the paper filter it will destroy it. Can we replaced the housing assembly with the racor 645 housing assembly and filter. I will look at the R20s on the web.

Caribou1.... I look at the R20s and it does not look like the mopar at all also the racor645 that i mention i think is too big for the jeep; I was talking about the racor 445 housing assembly. I think it could work with the S filter.

Caribou1.... I just read in the KJ Service Manual on page 14-52 of the CD it said:- The fuel filter has a 3 micron element and tightens clock-wise to the housing.(fig.9)- so if the service manual is correct then we should not worry about it.

- The water in fuel sensing
- The preheating of the fuel for winter use.
 
The water in fuel sensor came with the CRD originally and screws into the bottom of the replacement filter in lieu of the drain plug that comes with the replacement, so the sensor is not lost. The sensor is just 2 electrodes in the plastic that measure the conductivity of the water if high enough.
 
The preheating element is not in the filter itself. The original filter I disassembled was simply a canister with a filter element. The canister extends well below the filter to provide room for water. Is the heater in the housing that holds the filter?
 
I would prefer to use a Racor with a clear bowl. I contacted Racor about a year ago and they said that they thought the R20S(if memory serves) would work but could not say absolutely so I did not order one.

-There are two connectors on the clear bowl.
-Both heater and water sensors are located inside the plastic bowl.
-The R20S filter cartridge has a 'chamber' for allowing a volume of fuel to remain around the heating element.
 
European 4x4 clubs promote Parker-Racor filters when preparing for African rallies. When you're not certain of what will be poured into your tank, you add another filtration element to the one I received with the truck. My fuel filter element has 20,000 miles and doesn't show any sign of fatigue.
The plastic bowl is really neat to detect the presence of water: I apply a flashlight underneath the bowl, next to the connectors.
When illuminated, the colour of the plastic bowl full of fuel is like tea (or american coffee )

Bou, I am having trouble making the connection between what you have and what we have. I have no heating element that extends into the filter. The top of the filter looks a lot like an oil filter with no chamber. Are you saying that one of the plugs from the filter housing can be moved to a connector on the Racor filter? I only have one electrical connection on the filter itself and that is the water sensor. Right now I am just looking for a quality inexpensive replacement for the factory fuel filter that is easy to find. The Jeep dealers around here are not real big on keeping the stock filters in stock so a WIX from a local parts jobber seems like the way to go. I am not closed minded to something better it's just that sometimes a complicated life takes the easy path.
