I believe your motorhome has as Cummins engine?? If so, there should be a Fleetgard filter that will work for you. Call either REV group, that now makes Monaco's or Cummins to get the Fleetgard number.

On our 1997 Windsor we replaced the original Winn fuel filter with a newer Racor unit.

Are you referring to the clear fuel pre-filter?

Replaced the old Winn with Racor 700 Series very easy change out, may have to drill one mounting bolt.

My Winn was bypassed when I purchased. I also replaced with Racor with hand pump 120 GPH Marine diesel version ...bigger filter aluminium bowl . I got a sweet deal NOS from eBay.
My understanding is that seals for plastic strainer are the unattainable items for the Winn system.

I had trouble matching or sourcing those o-rings. You can still buy the pre-filter part and it comes with the o-rings:
Winn 300200
My Winn system was sucking in air and leaking fuel through those o-rings. Eventually the final fuel filter in the chain filled with air and I lost fuel to the engine. I purchased a new pre-filter through Auto Safety House in Holbrook, AZ when I broke down in Winslow, AZ (they had to order it but it arrived next day). It works perfectly and was nearly trivial to replace.
You might as well replace that filter with the o-rings since the filter housing is clear plastic and you'll be worse off if it breaks at some point.

Hmmmm. I thought read there were some beveled rubber seals somewhere that are not replaceable. I thought it was plastic filter bowl. I know Racor made a nearly or exact duplicate of my green painted Winn filter system circa 1995. Everyone just said to forget it stay away from trying to resurrect it. I believe the Winn water sensor will work in bottom of Racor bowl.

I'm certainly not an expert on the Winn fuel system so if it's giving you grief somewhere else in the line then it probably is best to replace it at this point. From what I have read a Racor system is mostly a drop in replacement with no change in performance from the Winn. The mechanic that I work with suggested an AirDog fuel system. Since you and I have mechanical engines, he said it would be easy to do and make a huge difference in economy and performance. I plan to give that a bit more research time in the future.

The system strains then filters fuel .Has elect priming pump ,push a button bleeds off water or air and has water alarm in lower filter bowl. It's not like lift pump it's helps priming fuel system removing air lock after changing filters or running out of fuel.
