There can be only one. Most efficient fuel filter.

Eureka?
I have found it, maybe. A wix fuel filter with a beta 1000 ratio of "less than 4 microns" with a 3/4-16 thread so that means I can get a filter head for it.
Is this the ultimate spin-on fuel filter?

My previous best had a beta 1000 of 21 and beta 2 of 1mu. I spit on it now. Ptuu.

Have you a part number or are all WIX fuel filters the same?

The WF10429 one would work?

They're definitely not all the same. Some are rated for 10 microns, some up to 30.
I've goty filter crossed. It's beta 75 is less than 4.
I really wish they'd post the same bata ratios. Donaldson likes beta 1000 (so do I).

This one might be better. I think they're used on later Detroits with electronically fired injectors.
Only problem is it's a 13/16-12 thread.
Can I get a 13/16-12 thread filter head?
Probably.
Its glass and glass usually does better than paper in the efficiency department. But in the cost department, not so much.
