Well, he may very well be. I really can't see why he couldn't. It's just an odd selection unless you just happen to have a spare fuel filter base hanging around. The filter has a 10um rating in WIX and it is the extended duty version. In this capacity, I imagine a number of hydraulic filters would do well too.
Descriptions: Fuel/Water Separator Base
Notes: This base requires the D-Ring, furnished with filter, for installation. Permits the addition of a remote mount fuel/water separator spin-on to most equipment. This is standard Cummins engine fuel filter mount.
