fuel filter question

JDaPP · **Posted:** Thu Jul 02, 2009 8:07 pm

Coming home from work today the jeep did not want to get up to speed on the interstate. It would make it to about 50 max and to get there I had to push the pedal all the way down and then release to help make it shift. I had a P093 code so I suspect filter/air in the line (my problem was very similar to http://www.lostjeeps.com/forum/phpBB3/vie ... =limp+mode.)
I had a fuel filter and went ahead and changed that. Now while bleeding the air from the system diesel comes out of the plug where the heater (red wired plug) goes into the filter head. am I now going to need to get a new filter head? or what are my options? ( I am looking for least costly so upgrading to a different filter type or a lift pump are my lowest priority)

Chrysler redesigned the fuel head - the new one doesn't appear to have the leaks
Mopar Parts America has the head (seperator) and connector for ~$100

not the best pic, but you should get the idea:

and for those of you interested in the part numbers for the new:

Separator 68043089AA
Connector 68043086AA

make sure they order the connector too

new installed on the left .. old set on the right for reference

now a Racor would get a leak fix and a better filter - but it's more expensive.
and the lift pump is a really good idea - but it's not a replacement for fixing the leak.
(it is a really good addition to fixing the leak)

Thanks for the info. Quick question for anyone, I read on one of the posts that Kccrd "left the heater plug unplugged and filled the space with pure black silicone that should fix the problem forever" (http://www.lostjeeps.com/forum/phpBB3/vie ... ght=heater) Is this a viable solution until I can get a new filter head? are there any issues I should be concerned about if I do fill the plug with silicone?
also once I get the filter head assembly can I just leave the heater plug off (I know many have done this)? What are the repercussions? [/quote]

You should be fine if you unplug the heater, and fill it in.

Your going to want a fuel heater though. It only takes about 2-3 days to get the parts at the dealer.

Here is the new part # 68043089-AA fuel separator 68043086-AA wiring kit no charge all 4 time I replaced mine. the last one they even gave me the new filter. I just had to take them back the defective part less the filter. that was last November when I had 96.000 miles on the clock. This was the dodge Chrysler Jeep dealer in Olathe ,KS great guys to deal with.

Well I called the dealerships in the area just to see if they would exchange it like they did for Kccrd, being in San Diego they did not want to touch it (one dealership recommended that I take it back Nevada for service, because they are "illegal in California"). The next dealer said that he had only ever seen one and wouldn't know what to charge me to exchange it (I would just have to bring it in and leave while they figured it out) I intended to install the filter head myself, but wanted to see what they would charge, but after hearing these guys there is no way I would let them touch my vehicle (the first dealership said they worked on cummins and GC CRDs alot so they might could figure it out). So thanks for the part numbers, and does anyone know of any decent diesel mechanics in San Diego in case I have a problem I can't fix?

All you have is 2 small hose clamps to remove and 2 13mm nuts to remove and the head unit comes also disconnect the 2 connectors then you can lift the unit up enough to unplug the water in filter wire and reinstall the new unit but you have to fill the new filter with fresh diesel or bio diesel of your choice so you do not have to pump very much to fill the filter. You will have to unscrew the old water sensor from the old filter and install in your new filter and then reconnect that wire. then hang the new unit on the 2 bolts on the fire wall and tighten the nuts back on and your done. My order is a little out of order but you get the picture.

What is the main advantage to the RACOR unit?
Is the RACOR filter better then the CAT filter that some are using?

Chrysler filter 3 microns

Wix replacement 10 micron

Racor filter 2 micron (if you order the right number)

Cat filter 2 microns, but adapters no longer being made.

Making an adapter to screw the Racor filter onto the Mopar head is on my list, but Hunny Due is way ahead and growing every day.
My preliminary findings are the Racor is 1" X 14tpi and stock Mopar is 16mm X 1.5mm

Bore and tap a 1" X 14 TPI ready rod with a 16mm X 1.5mm tap, then cut it to length.

As long as the gasket is compatible it should work.

How did you verify that the Chrysler filter is 3 microns? I'm on my second Wix (NAPA) replacement filter and I'm really wanting more protection without having to modify the fuel head. No air-in-fuel problems, knock on wood.

It's probably elsewhere, but I'm pretty sure I've read in the service manual that the Mopar filter is spec'ed at 3 microns.

See, I thought that the Wix/ NAPA filter was the same as the Mopar filter - since NAPA supplies OEM parts and the NAPA filter is made by Wix. . .

In the FSM, Onthehunt found it and pointed it out, read it for my self.
Specs on WIX is what they publish in their catalog.
