Yeah, they have a couple of options. Go to page 50 of this documet for the details: http://www.donaldson-filters.com/070616.pdf

I like the idea of having the 3 μm filter/water sep unit before the OEM filter/WIF sensor, which is what I'll do when the CAT 1R-0749 needs changing on my Dad's and brother's Duramax's.

Of someone is running dual Nicktane filters (wheel well & OEM adapter), they could run a 10 or 20 μm in the wheel well, and the 3 μm on the engine. That would provide for a long service life on the filters, and dual water separators. Add a lift pump and your injectors should last a long long time.

If anyone is looking for something even bigger, the Cat 1R-0755 filter is 2 μm absolute like the 1R-749, but it's 46% larger in diameter, and 29% taller than the 1R-0749, and has 1-3/8"-16 threads.

The volume of the 1R-0749 filter is 100 cubic inches, or 0.43 gallons.
The volume of the 1R-0755 filter is 273 cubic inches, or 1.18 gallons.

There are three filter heads I've found that will work for the Caterpillar 1R-0755 filter, the Donaldson P174777, Fleetguard 3304173S, and the Baldwin OB1308. 1"-14 filter heads for the 1R-0749 are everywhere.

The Donaldson equivalent for the 1R-0755 is a P551316, and it's not a water separator. However, the P550348 is a separator, but it's 7 μm absolute instead of 3 μm.

Here is one more twist on the "micron" ratings stuff. Apparently, there is a new testing standard on filters. This method cannot test anything less than 4 μm. So, Caterpillar now has a new line of filters dubbed "Ultra High Efficiency," that go beyond the "Advance Efficiency" of the 1R-0749 and 1R-0750. Here is Cat's page on some of the parts: http://parts.cat.com/parts/filters/f...igh-efficiency

I read about it over in the Cummins Forums, where a lot guys are trying to retrofit these to their trucks. The thread I've browsed is here: http://www.cumminsforum.com/forum/3r...-can-done.html

Here are some pics of the UHE filters:

Just in case anyone has considered adding a Cat Ultra-High Efficiency fuel filter to their set up...

So after about 2 hours at the local Caterpillar dealer, I finally got a list of parts to retrofit a 364-5287 UHE fuel filter to my pickup. The 364-5287 is an “ultra high efficiency” upgrade to the “advanced efficiency” grade 1R-0749/1R-0750/1R-0751.

The most recent filter testing standard, SAE J1985, doesn’t test below 4 microns, so there is no “standard” to test these “UHE” filters against. The popular 1R-0749/1R-0750/1R-0751 are “advance efficiency”, so the UHE filters go beyond those in terms of micron ratings. If space is a limitation, you can also use the CAT 306-9199 filter, which has less capacity than the 364-5287. I would not recommend using these on the vacuum side of a lift pump. You'll likely need some pressure to get the proper flow through them.

The smaller UHE filter (306-9199) is used on 3116, 3126, C7 and C9 industrial engines, up to 360 hp/ 925 lb-ft of torque, so I feel pretty good about it, and the filter head, feeding enough fuel to my engine. I even found it being used on a C15 engine (926 cubic inches) on a generator set.

The filter head is part #141-5138, it was about $40; sorry I can’t find the receipt so I don’t have the exact price. The top of the filter head has a place for a manual priming pump, which I blocked off with a cover, part #6N-4414 ($11.42) and gasket #1P-0436 ($1.39). You’ll need two bolts to secure it, part #6V-2315 ($0.26) and #6V-5218 ($0.37). Yes, the two bolts are different sizes, but the CAT bolts have a nice oxide finish to them.

There’s also a place to plumb in a fuel pressure sensor if you like, but I plugged it with part #9S-4182 ($8.25). That plug seals on an o-ring, which is part #6V-5048 ($3.49), which is rated for fuel use, but I don’t know if it will resist bio-diesel. Sorry, I don't have the size for that plug.

Finally, the inlet and outlet are also o-ring seals, and those o-rings were part #3J-1907 ($0.89), and you’ll need two of those. These were the fuel rated o-rings recommended by CAT. The inlet and outlets are -6 Straight Thread O-Ring (STOR), using 9/16-18 UNF-2B threads.

The threaded stud on the filter head is 7/8-14, and the inside hole is 0.372” in diameter. The most restrictive part of the assembly that I can see is the cover plate for the fuel primer pump which is 0.312”, but I might run a drill through that to open it up a bit.

The head has two mounting holes, 0.36” in diameter, and 3.415 inches apart (outside edge to outside edge).

Below are some pics comparing the CAT unit to a NAPA 4770 with Donaldson P551313. The CAT 364-5287 is 3.4” in diameter, the P551313 is 3.675”. Please note, these two filters are not interchangeable, they’re just here for size comparison.

Thanks for that info btw...

My AD-II-165 will be here Friday
So has anyone found a good cheap source for the cat filter 364-5287?

my local Cat dealer wants $32 + shipping...said the only place his computer shows a couple are in Illinois...

If they are that pricey and hard to come by then I may just stick with the Cat 1R0751...

I will be offering nipples to use the UHE cat filters with both my auxiliary filter kits and my OEM adapters. Any customer who has purchased one of my adapters or auxiliary kits using the billet head will be able to do a simple nipple change.

i just recieved my oem adapter w/ cat filter #1R-0750 its still on the bench whn will nipples b avail for the uhe filters? r thy water seperators as well?

The UHE filters are not water separators, Cat only intended them to be used as a secondary filter, after the fuel has already gone through a Primary Filter/Water Separator. Also, the UHE filters have a higher level of resistance than the 1R0749/1R0750 filters, and while I have no evidence to back it up, I image they would perform quite poorly on a vacuum situation. So unless you have a lift pump, you're venturing into uncharted waters.

yea def, im just gona stick w the donaldson fuel/water seperator w bowl. thn whn i get my airdog in ill change it around.

[Diesel Power]

probably a month. they are being machined right now.

Looks like the Donaldson filters I mentioned were a hit.


Please let us know if you use a Cat UHE filter on a vacuum application, I'd be eager to put those on my family's trucks if they work good.
