2007 KW w Cummins ISX - does it need the fuel water separator

My 2007 KW T600 Cummins has both the regular fuel filter and the fuel water separator (FF2200 and FS1000). In talking to the dealer, some guys run 2 FF2200s instead of a filter + fuel water separator.

The reason I ask is that in winter with biodiesel the FS1000 gets clogged pretty #### quick, like 5000 miles.

It's easy enough to change but just a hassle.

Any problem running the two FF's in the winter? I know the FS1000 is a really small micron so I'd lose some filtration.

By the way, 1.7 million and still running strong.

thanks

 

Filter cost about 15 bucks. A set of injectors is about 3000 bucks. Saving a few bucks now can cost a lot more later. Do you have any other fuel options?

 

Unfortunately not. I guess I'll deal with it and just put it on a schedule.

 

I avoid biodiesel. Setting along the road switching clogged filters not on my agenda, especially in the winter. Think that biodiesel program is a taxpayers burden.

 

Davco 382 with;

-Coolant heat option
-12V heat option
-120V heat option


Problems solved !!


Don't degrade filtration just so you're not changing filters, that's idiocy. Most extreme example would be running without filters.

Fix the problem and UPGRADE your filtration ....

 

I don't have it on my truck. I remember having it when I drove someone else's truck...So you just swap it with the existing fuel filter or there is more to it?

 

Generally you want to add it before the factory spin on filter.

You can get a wide variety of filters... I would recommend the plus size filters to reduce your need to change them...

On a 2007 truck , a 10um filter should give you good service, easy easy to change and cheap. Buying them by the case helps too..

I usually run 2um or 7um btw , the 10um is my minimum.

 

How's that different than running two metal encased filters? On detroit 60's they only run the one Davco filter.

 

Cheaper and you can visually see when to change the filter and you have options for uM of the filter...
Also the heat options are far better

One Davco can replace everything else because of filtering level selection.
Example, I usually run the plus size 2um or 7um filters. The 2um is far superior to the factory metal spin on filters. (Minus the CAT UE filters)

 

I know this is an older thread, but I can’t post a new thread before a few more posts lol. I have a 2009 389 Pete with the ISX in it. Every other truck I’ve driven has had the open element (Viewable) filter on the frame rail plus the factory screw on that’s mounted on the motor. My truck however has a metal cased FF2203 on the frame and a 2200 on the engine. Haven’t seen much info on this elsewhere. I guess my question is how hard would it be to convert to a viewable filter with a water separator?
Thanks
