I never intended to have 3 filters, but after being stranded at -13 at 1:30am because of a gelled/iced filter, I decided to get the lift pump with fuel heater. I was running the Donaldson P553203 on the CAT adaptor at the time. I haven't have a problem since and I have great filtration.

Diesel fuel is inherently dirtier than gasoline, and your Donaldson is so dirty because those FS filters you're running don't have a very fine micron rating (most separators don't), and the Donaldson is taking the blunt of the dirt.

They're dirty, but not bad. When the element collapses you went too long :rofl:
Maybe run some antimicrobial additive but I don't see it being an issue.

FYI Fleetguard is built to "Cummins' specs" because Fleetguard IS "Cummins Filtration". One in the same.

About a bazillion websites need to changed, the CAT IR-0750 filter is not a 2um more like <4um, the black stuff is not dirt it is asphaltenes.

CAT filter specs page 11, the 1R-0750 Advanced Effiecency

Thank you. I've often thought about doing away with the CAT and running the p553203 on the factory head. If the lift pump fails and bypasses I would be running without a water separator with that CAT filter. I think the Donaldson is a 3um which would be better than the CAT according to your link.


I don't run additive in the summer but in winter I use Schaeffer's Diesel Treat 2000.
