Auxiliary fuel/water filter & fuel filter

[rfitzgarrald]

I just installed the kit from dieselfuelfilterkit.com (2 micron). I’m getting ready to change the stock fuel filter & water separator. How often should I replace the stock filter (fs2) now?
The Baldwin bf1212 & CAT 1r 0750 recommended replacement interval is 15k depending on fuel quality. The Fleet Guard ff5320 says 2 micron, talked to cummins and told me 5 microns. Stock filter is only 7 microns, cummins recommends 4 microns. Huh!

This is what I found after an internet search:
Fleetguard FF5320 High Efficiency 2 Micron Diesel Fuel Filter
This diesel fuel filter is a genuine replacement Fleetguard FF5320 High Efficiency 2 Micron Fuel Filter. This diesel fuel filter ensures the maximum protection of your entire fuel injection system by filtering down to a 5 Micron level. The Fleetguard FF5320 High Efficiency 2 Micron Diesel Fuel Filter fits numerous applications as well as being used as a cost-effective replacement for the FASS Titanium Fuel Filters.
What, I’m confused ? Gonna stick with the CAT filter.

The FF5320 is indeed a 5um filter that says for 2um applications on it.

2um is a bit of a misnomer anyways, at it hasn’t been a actual filtration value for over 15 years.

The 1R-0750 is a 4um filter on current standards, which came out in 2004. It’s a good filter, but was not designed for HPCR applications.

The filter to run is the FF5814. It’s the same thread pitch and will easily fit in place of the FF5320/1R-0750. It uses the 3um nanofiber media found on the newer OEM filters. I’m not aware of a better filter media for HPCR.

For a f/w sep the Baldwin BF1212 is perfect.


The upgrade Filter-in-Filter for the 07.5-09 6.7 is rated at 5um.

Thanks, now I have an alternative p/n along with clarification.

Has anyone run this in the winter or In colder temps? Wondering if there’d be any gelling problems.

I have had the Glacier Diesel Big Line Fuel filter kit on my truck, installed in 2010 at 30K. I have use only the FF5320 filters since I purchased a case of them back in 2010. I have never had a gelling issue with the secondary filter when is use. I do live in northern Il and have experience some cold weather temps but, nothing like AK. The truck is kept in a garage attached to the house when not in use. I do use a winter front and block heater from Nov1 till March 1 on the truck. So, the engine heat is trapped around the filter in the winter. See attached pic.

I’ll have to check that one out. Thanks for the reply!

Jim did you keep your stock fuel filter in place and add this filter or does it replace the stock filter altogether?

I've been running a home made version of the dual filter setup that's mounted in front of the fuel tank since 2010 without any issues. My truck is parked outside and the filters are exposed to whatever mother nature throws at them. Here in Wyoming, winter temps can be quite bitter at times and I've seen it get as low as -42* and I haven't had any gelling issues yet. Thankfully, all the stations in this area start ordering winter blend in mid October.
