Question for AH64ID

[mwilson]

As you may have seen I am trying to see if the 3rd gen 6. 7 trucks can be converted to a drop in fuel filter. I have started researching the 4th gens but it looks like a lot of plumbing changes.

I am thinking about comparing parts with my 3rd gen 5. 9. That may require less parts.



BUT, is the level of filtration needed available in a 5. 9 drop in filter style before I go all through the parts comparisons???



You are the filter man so I await your reply.



Thank you.



Mike.

AFAIK there is no drop in filter with a 3 um absolute rating, 5 um is the best available.

The new HD's are supposed to have multiple filters with what was advertised as a 3 um filter but not sure if that was a spin on or cartridge, or, if it was absolute or nominal.

That's my concern, I don't wish to send anyone in a bad direction. I'll keep poking around the 4th gen style.

The OEM 6. 7 filter is better than the OEM 5. 9 filters, and the OEM 6. 7 is as good as, or better, than the PF7977 for the 5. 9 filter housing.

I have a oem 6. 7 filter canister that I was thinking about retrofitting onto my 2005 truck for the better filtration/water removal that the newer filters offered over the 5. 9 oem filter.
But then I got a great deal on a Mopar SDFK on the frame as well as a GDP 2mic kit mounted on the cylinder head, so I got MUCH better filtation and water removal then even the 6. 7 filters offer. While I COULD still mount the 6. 7 cansiter on my truck to take advantage of its water stripping abilities, I realized that the prices of the filters on the 6. 7 are THREE times as much as the 5. 9 filters, so I will likely NOT do that, even though I love the idea of adding 6. 7 parts to 5. 9 trucks. I still have the 6. 7 canister, though, as well as an extra 5. 9 that I could compare it to side by side. IIRC, one would need to at least update the feed and return lines to use the 6. 7 canister on a 5. 9 and maybe be easier to do the entire rail and manifold for other fuel/air advantages as well. GDP DOES offer a kit to do so. If you want I could post some pics of BOTH canisters side by side.

Here is a link to what I did on my truck--

You don't need to use the 6. 7 housing on the 5. 9, it gains nothing. A comparable filter is available for the 5. 9 housing.

I am not sure it's MUCH better, the f/w sep is a 25um filter and has the same f/w separation ratings as the 6. 7 filter, and that Baldwin filter you have is 7um, which is worse than the 6. 7 final filter (thou I did see you have plans to replace it with a 3um Donaldson). A Mopar Severe Duty kit with Mopar filters still offers less overall filtration than the OEM 6. 7 filter, but does have an extra f/w sep.

I have the Mopar kit, and think it's a great kit and does provide increased filtration over a single filter just in terms of staged filtering and 2 f/w sep's, but I don't think I would call it MUCH better.

I've been following some of the fuel filtration threads and read the comments in the register about the Severe Duty kit vs the likes of FASS/Airdog and will likely do a SD kit but the only part I'd really need from Mopar is the mounting bracket that is used. Here's a filter head I found that is appears to solve the filter commonality problem. It is supposed to have 1-14 threads according to one person I talked to at Cummins filtration but still need to confirm as this is what I would prefer to work with.

This head is Fleetguard PN 3930335S (about $110 from Peterbilt parts). If it truly has 1-14 thread, it can be coupled with a FS19596 FW separator which is in the 95% removal range for free and emulsified water and comes with a WIF sensor. A Fleetguard 3934304S pigtail is about $15 @ Amazon for connecting to the heater along with a 68020643AA WIF harness and the rest is miscellaneous hardware/hoses/fittings. The FS19596 filter has a Beta 75 rating of (98. 7% efficiency) for 7 micron particles. It is a bit long and a shorter one with a WIF sensor would be better for clearance, but this base will accept quite a few other filters.

I want to put this ahead of the factory filter then use a Cat 416-1225 UHE Beta 75 rated 4 micron unit between the factory filter and the CP3. Will confirm when I know more.

You can easily make your own bracket.

As for the UHE, it uses a different thread that most filters and if you find yourself in a bind needing a filter you may not find it.

The Donaldson P551313 is a 3um Beta 75 filter, and there is a new Fleetguard that is in the works designed for HPCR's that is going to be 4um at Beta 200 (ISO multipass that seems to be the new rating scheme for HPCR's, I still don't understand why it's multipass???) FF5814.

Once it's released I will be running the FF5814.

So, if I understand, the FF5814 will be a Cat final filter using the NanoNet media? Do you think they will come up with FS19856 but with the NanoNet media at a good u rating? I think that would solve a lot of problems in a simple way.
I recently saw a print ad that I can't find online showing amber colored fuel flowing into some of the nanonet material and crystal clear fuel coming out. Very impressive.

I haven't seen a release for the FS19856, but it would be nice.

The Cat 416-1225 is the Ultra High Efficiency version (synthetic media) of the Cat 1R-0749 (advanced efficiency, cellulose media), so they use the same base as a Donaldson P551313 (1-14 threads, seal ID = 62mm, OD = 72mm). Unfortunately the closest shorter version of a 1R-0750 Cat is the 362-5287 but it comes with 7/8-14 threads, not 1-14. There is a Cat base with a replaceable thread bung, but it is a hassle to do it. Cat offers 3 different levels of filters: standard, advanced efficiency, and ultra high efficiency. They don't publish micron data none of the filters are rated any lower than 4 microns now, but were down at 2 -3 microns before the testing standards back in about 2000.
