New 3u fuel filter. Anyone using it?

[Radshooter]

I found this link on another web site. Looks interesting. Just wondering if anyone is running it yet. I am thinking about ordering one and trying it out next filter change, but I just changed filter a few weeks ago.

Anywho. . if anyone has experience with this filter, let me know.

Thanks.

Edit: I went to their website for more research/info, and when I put in the part number for product search, it doesn't find anything. Maybe they are not making it yet? Did I search wrongly?

Wow! 3 micron Now thats something worth trying. Guess I might have to pick some up. I've been using Baldwin filters for a few years haven't had a problem yet though I had been running Biodiesel till this year (price went too high can't find any) Now with the ULSD plugging up all the injectiors I've read about on here I might have to change my thought process...

Which Baldwin are you using, the 7977? If so, how much are those a piece? TIA!!!

I don't know if it's true, but an earlier thread indicated that going smaller than 7mu would defeat the water separation capability. I don't understand how/why, but that was the assertion.

I just had a conversation about the new 3 micron drop in filter with Reb Brown from Brown's Diesel Service. Reb was telling me that they had just come out. Not sure of brand (Fleetguard, AFE?) but for folks only using the OEM cannister filter, 3 micron seems the way to go.



I am currently using the 7 mic in the cannister and then the 2 micron Fleetguard spin-on with a Walbro pump. Next change, I'll go with the 3 mic in the cannister.

I would wonder what the fuel pressure would be with a 3u filter and the stock pump. I can easily drop my pressure to zero with the stock pump running fuel thru the stock 10u filter and a secondary 2u Donaldson final filter. I run the stock pump now when I get low on fuel so as to keep the Walbro from sucking air. When I switch over, I have to drive fairly easy to keep pressure up.

Interesting... .



That would be good news. the PF7977 is 5 microns, and thats pretty good... Personally I run a 2 mic Cat between the OE filter bowl and the CP3, as well as a 20 mic water sep between the tank and the OE bowl.

Radshooter, the first page of the PDF says they are accepting preorders, so it appears that it is not released yet.



Just saying 3 mic really does not mean much unless they tell you all the specs and what test protocol was used. Forget the advertising hype, wait until they publish some real data to back up their claims. And make sure their results are from a single pass test.



Here’s a page explaining basic filter stuff Filter Manufacturers Council - Heavy Duty Diesel Fuel Filters



Note the section where they describe running multiple filters (primary and secondary). If you already have a relatively large capacity 2 mic filter, then it is more or less a waste to use a smaller capacity 3 mic in the stock housing. Just use the 7 or 10 mic to get the big stuff and let the 2 mic do its job. Otherwise you’ll be changing the 3 mic frequently and rarely have to change the 2 mic.



Tinman has hit on a issue that it seems no one considers; resistance to flow (or back pressure if you like). Remember the TSB which outlined specs that the stock fuel filter must meet, such as dirt holding and cold flow, etc? When using the stock lift pump these specs apply to whatever filter being used. When using multiple filters it is worse because all the filters’ flow resistance must be added together to find the system’s total resistance. If it is too high the stock lift pump may have trouble keeping up, especially when it is cold out!
