given that our (new to us) CRD Liberty has had what I would call 'spotty' maintenance, and came with no records, is there any way to determine whether the filter housing is original or has been replaced? Part numbers?

I now am the proud owner, as of two weeks ago, of a '05 CRD. Just FYI, and this info is second hand from powerstroke nation. One of the supposed reasons the heater is in the powerstrokes is that when it is left unhooked, the fuel will start to leave a "wax" type coating on the components and eventually restrict them. Im sure some may be able to get away from leaving their heater unplugged, but there seems to be enough talk about it in other diesel truck forums that I would much rather spend the money and get an upgraded filter head with a heater element($200) instead of replacing injection pump and injectors($2000??) and thats parts only. Just thought i would share the info. Dont shoot the messanger.

my 2 cents,
Corey

I've been going through my 2006 KJ CRD (Cleaned MAP/MAF sensors, replaced fuel filter *again*, and did the elephant hose modification due to the amount of tar built up on my sensors) because of a check engine light that I've had. Which is now reading a bad glow plug...I called our dealership and they wanted to charge me $1048.00 for four new plugs so I ordered the Etechno GX3123 from Italy and they will be shipped to me in Canada for under $200. Stoked. Hoping that will solve the CEL.

Now...back to this topic...I'm in Canada, it get's crazy cold and I'm worried about the fuel filter head. I've been checking it and the fuel filter heater connection looks great, but I think after reading through most of these posts I'm going to go ahead and order the new Mopar replacement and splice it in. You've all convinced me!

Thanks to everyone on here for all the great information!

Cheers from cold and snowy Saskatchewan.

The wires to the heater and to sensor both have to be spliced in (heater plug is slightly bigger too). I believe that the write-up is in the CRD Tech only section of the forum. However, I cannot navigate forum as well as a I used too. I've owned mine since new. With this forum, you can do most of the repairs and general maintenance yourself.
Good luck,

The reason my fuel head was replaced was because I did not want my rig to catch fire. The male plug did that went into the receiver (female unit on the head) did show signs of heat and the plastic was mildly melted. I'm not sure of your wax issue, I've never had a problem.

Good luck,

Just to get it out there on the 2n gen fuel filter head all the ones I've seen the new heater element plug is bright blue. The wiring pigtail colors don't match the OEM wiring; just hook the wires up based on size and you will be fine.

Part #s and pictures are in the first post, scroll down a bit, on Sir Sam's NOOB guide.

Just a reminder to check this if you still have the original fuel head. It took 8 years, but mine started to melt slightly at the plug. Already had a 2nd gen head ready to go.

I've academically gone though this whole thread but still feel the need to seek advice.

My second CRD, just recently purchased, has 160,000miles on it. I just added an in-tank lift pump and used a custom harness from ID Parts (excellent t by the way). The pump seems to function fine. After the first drive a noticed a burning smell and found d this fuel heater plug had burned badly and now leaks a lot of fuel.
I should have had it unplugged from the start. I will be replacing it and I understand all that.
What I'm curious of is if this was mere coincidence or if the in tank pump caused this failure?
Is the pump running wrong? / Too much pressurve?

Not too much pressure; but by adding the in-tank lift pump any leak that use to allow air to be sucked in, now will puke diesel fuel out that leak.
The plug-in for the fuel heater on the fuel filter head is a common problem and the factory actually issued a service bulletin about this problem.
The correct fix is to replace the fuel filter head with what is called a generation 2 filter head that has been redesigned to address the leaking plug connector.

But you really did the right thing by adding a in-tank lift pump! Now any leaks are self evident and easily found so they can be repaired...
And no more air in fuel worries and the Jeep will run and perform better by having the in-tank pump installed...

ps: lots of locations sell the second generation fuel head, just Google it! :google:

I recently had to replace my fuel head because where the bleeder valve threaded in, it had a hairline crack that sheared off. So i had to buy a whole new head. Since they only sell the complete kit: filter, new wiring harness, heating head and fuel head I have a bunch of extra parts because it appears the wiring had already been upgraded by a previous owner. So if anyone's interested I have:

New wiring harness, fuel filter and the heating element portion of the fuel head I will sell...likely dirt cheap since I don't have high hopes for being able to unload it. Full disclosure, I had written 193,500 on the fuel filter I had bought. Since the new assembly came all put together, I didn't see the need to uninstall the Mopar fuel filter to put on the one I was installing before I discovered fuel head was bad.

Hey, how can i tell if it's been replaced or not? I just bought a used CRD and am trying to see what the previous owner has done and hasn't done.

Easiest way to tell:
Has the OEM fuel heater plug/wiring harness been modified/replaced? Harness cut and new connector wired in place of the OEM connector?
