Better fuel filter than 7 micron? Dodge OEM Severe Filter kit PART #68083853AB

[navyjoe]

I have a 06 with 75000 miles. Somewhere I thought I read in the TDR magazine that the 06 existing lift pump could not support a higher micron filter than the stock 7 micron.

So 2 questions.

#1. Some threads seem to indicate there is a "better" ie lower micron filter available to replace the stock 7 micron stock filter. If that is true who makes it?

#2. The Dodge dealer offers the Dodge OEM upgrade frame mount filter for $112. The dealers ad suggest it should work with the 06. The ad reads:

"PART #68083853AB - FITS 2004.5 TO 2007 DODGE RAM 2500, 3500 & 3500 CAB & CHASSIS EQUIPPED WITH 5.9L CUMMINS DIESEL ENGINES NEW! SEVERE-DUTY DIESEL FUEL FILTRATION KIT"

Where does this factory kit fit into the scheme of things??​

The oem LP on my 2005 is pushing through THREE filters, the last on being a 2 mic Donaldson mounted right before the CP3. It has zero problems amiantaing lift pressure at 9 psi, which is plenty.

The Baldwin PF7977 is the BEST filter that will fit into the oem fuel filter canister.

$112 for the SDFK is a good price, BUT you might well be stuck buying only Mopar filters for that one as IIRC they *******ized the inlet size on it.
The original SDFK for 3rd gen trucks that I mounted on my truck used a very standard 1-14 TPI inlet on it, so you can choose from MANY different filters for it, but those are no longer available and have been superseded by the newer one.

Do you moniter fuel psi? I added a aux filter after the oem and use the 5 micron in the oem can
I didnt know if the in-tank LP will do three filters... Is the 'first' filter pre-oem can? 12 micron baldwin?

On my truck, the first filter is frame mounted in from of the fuel tank, over the transfer case skid plate. Ity is the ORIGINAL SDFK that Mopar sold for third gen trucks, including the first 6.7 CTD. When they "upgraded" to the newer SDFK ( AFAICT it was only to make the filter inlet size more proprietary and prevent users from buying other brand filters), the original SDFK hit the greenmarket used parts and I picked a couple up for $50 each and then installed one on my truck with a 20 mic "trash" filter with W?F separator and sold the other to someone else to cover some of my cost. My 2005 original LP has been pushing through the 20 mic, Baldwin PF7977 7 mic, and Donadalson 3 mic for two years now and easily maintains 9 psi at idle. (knock wood lol) All that being said, it IS time for me to change the filters. Here is a link to my install thread--

Trying to find out if the kit that NavyJoe posted is the newer or older SDFK…meantime, found a GREAT price on it $57.12--

I run a very similar, or identical, setup as seafish. Three filters on my OEM lift pump with adequate flow and 2 of the filters are under 7um.

The tighter filters don't effect flow until they have become restricted. I have been able to get 30K miles out of a set of 3 filter without any real noticeable restriction. Having an initial 20um filter really helps.

Ahh, always the catch. I see the replacement filters are about $60 !! Thanks for that info

THANKS! I'll look into this

Wow Seafish. I looked at your post on the filters, Nice job!

Does anyone know what the micron rating is on the Doge heavy duty pre-filter? For $60 you would think it could filter our frog hair.

 

[lpennock]

The old SDK was a 25um filter so I would guess the new one is about the same. Only good for keeping rocks and algae out.

 

[navyjoe]

Ha! OK, thanks. If that is the case its hardly worth the effort it would seem. Better to just change the main filter more often and possibly invest in a 2 micron post filter???

What about that "CAT" filter kit I've seen mentioned in various posts. Is it just a high micron pre-filter as well?

I replaced the stock 25um with a Baldwin BF1385SPS which is a 10um filter. I then run a Baldwin PF7977 which is a 5um in the stock housing. Getting the big stuff out with the SDK allows the small filter to last longer.

Whose pre-filter kit are you using?

Not sure I understand your question. I was talking about the original Mopar Severe duty filter kit. It came with a 25um filter that I replaced with a 10um. That is the first (or pre-flter) filter. The next filter is the stock filter housing which now as a 5um filter.

 

[navyjoe]

OK, that's what I was wondering. You have the original Dodge filter kit that has the universal filter thread. From what I understand the New Dodge kit forces you to use only their filter. Thanks.

You don't want a super fine first filter. What is want is a ~20um filter with excellent water separation ratings. The entire purpose of the first filter is to get the big stuff out to keep the super fine filters lasting longer. The more water separation you have the better as nothing stops it that is automotive approved. There are water blocking filters but I don't want one to stop my fuel flow mid grade

The cat filter is 4um, the Donaldson is 3 or 4um, as is the new Fleetguard FF5814.

IMHO the FF5814 is the best followed by the Donaldson P551313, and then the Cat 1R-0750.

For the initial filter I run a Baldwin BF1212 20um f/w sep.

 

[seafish]

NavyJoe, AH64ID is correct…the best diesel fuel filtration (or any filtration for that matter) is done by a "cascading" system of filters rated from coarsest to finest particles. This cleans the diesel most efficiently and ensures the longevity of the filters. It is SOP in a marine environment (miles from nowhere) , so you know that it is the correct way!!
