Ok,
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-0751. The most recent filter testing standard, ISO 16889, doesn’t test below 4 microns, so there is no “standard” to test these “UHE” filters against. The popular 1R-0749 & 1R-0750 are both “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 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 7.3L. 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.

This may be something that varies from Dealer to Dealer though. By using the above mentioned base, one can easily upgrade to the "UHE" filters with no trouble at all simply by changing filters. Seeing as the ever popular 1"-14 thread WIX base is $40 on its own, not including the filter, this definitely seems like a worthwhile upgrade.
