First off, no clue what a spin on fuel filter cartridge is, if not a Davco. Are you talking about the regular metal body fuel filter on the side of the motor? You have a photo if not either a Davco or regular filter? I would like to see one, as I am not familiar with anything else on the ProStar.

As far as filters, I would stick with Fleetguard, which is a Cummins owned company. That is all I will use.

Thanks for the photo

Sure. Hopefully I attached pictures properly. These are the 2 "spin-on" fuel filters I have. Maybe shouldn't have called them cartridge. Not sure why there are 2 but I replace them every 2 oil changes.

Thanks for the photo. Me, I would throw on a Davco unit, in place of the spin on you currently have, only because these new motors are so finicky. I like being able to see what is going into the engine, and the ability to drain the water off when I need to, as I have a visual means to do just that, especially in the winter. And it is right there, no digging into the side of the motor where the big fuel filter is, the one without the water drain. Davco units are all over the internet, around $250 +/-, shop around if you do get one, as there is not much to them, so no need to pay top dollar. Even a nice used unit from the junk yard would work.

As far as how often to change that little filter you currently run, I change the Davco every oil change, along with the primary fuel filter. If I get water in the fuel, and the Davco is working, sometimes that filter gets changed between oil changes. Sometimes it has been multiple times, as I can visually see what is going on. That is just me, but that Davco unit can really save the day when bad fuel is involved.

The Davco on my ProStar is mounted in the same location as your little spin on... A Davco unit should bolt right up.
