I don't see any data on the Baldwin PF7977 which is the fuel (5 Micron) I use in my truck.

chipmonk

that's the one i use as well. i called cummins filtration (the name of the company that makes fleetguard filters), and they are supposed to get back to me with the model #'s of the filters they tested.

I don't know what the BF baldwin filters application are for but it's the PF fuel filters we use. So compare correct filter to correct filter and the outcome will be different.

i use the pf 7977 (not listed in test), but according to the tech i talked to at cummins filtration, the baldwin filters they tested didn't do as well as the fleetguard equivalent in the single pass filtration tests, and in many cases didn't meet cummins minimum standards. just thought it was interesting info, and has been talked about a lot recently, on another forum. btw, the 'BF' filters in the test, are spin on type filters and not drop-ins.

The Cummins Filtration number FS19800E is exactly like the original filter that came on the engine because Cummins Filtration made the OEM filter for the Dodge Ram

Also, the ULSD version of the FS19856 is the same. The only difference would be the ULSD gaskets on the FS19856

Just remember that the Fleetguard FS19856 is a Stratapore 7 micron and the 19855 is listed as a 10 micron filter. IIRC Cummins wanted use to start using 7 micron filters back in June of 2006. The last time I saw any info it was researched and posted by (ah64id at dieseltruckresource.com ) about Baldwin , Fleetguard and other filters. From his research he reported that the Fleetguard Stratapore was absolute at 7 microns & 96% efficient at 5 microns and 14 gr. dirt holding capacity. Baldwin PF7977 is nominal at 1-2 microns and absolute at 5 microns and a 24gr dirt holding capacity. Both are good at separating water out of diesel. FYI, Absolute is 98.7% efficiency and nominal is 50% efficiency.

does anyone know if what cummins filtration is saying about baldwin's efficiency numbers being from multiple passes, vs. fleetguard's numbers being from a single pass, is accurate or just a sales pitch? they claim that their 7 micron stratapore filter gets better efficiency numbers than baldwin's 5 micron, in the single pass filtration test.

DBLR

The last time I looked Fleetguard had not listed the Baldwin PF7977 as being a filter they have tested. If they have not tested it yet how can they say its not as good as the Fleetguard?

chipmonk

they told me this is what they had found, when they tested other baldwin 5 micron filters vs. their 7 micron filters. it would be nice if they tested the pf 7977, but they said they hadn't yet. i'm not getting rid of my baldwins just yet.

NickBeek

Their argument is the single pass vs the multiple pass testing. It kinda makes sense to me. In the truck you only get one pass at the fuel before it goes into your engine. I m currently running the baldwin too. I called baldwins tech support and they confirmed that they use multi pass to test their filters.

chipmonk

i always figured that 5 micron was better than 7 micron, but all this single pass vs. multi pass stuff has me wondering. is it possible that a filter rated at 5 microns, doesn't filter as well as one rated at 7 microns? is it the multiple passes, that gives the baldwin filter the 5 micron rating?

DBLR

If Baldwin claims to filter out 5 microns or lager junk then is should not let anything larger then 5 microns pass through. Also 7 micron filter would let a 6 micron object pass where it should be caught in a 5 micron filter and not pass through to our injectors. BTW, I thought the Baldwin fuel filter was nominal at 2 micron and absolute at 5 microns. Absolute is 98.7% efficiency and nominal is 50% efficiency.

This is just more justification for me to invest in an aftermarket LP/filter setup.
