I've read several threads on the CAT filter adapter mod, but haven't been able to find any info on the effects of not having a water separator. Does anyone worry about water going through the CP3 or injectors? Does it hurt anything? I am just looking for some opinions before I do the mod.
If you're worried then use the Donaldson 3 micron with separator. I don't have the part number right now but I recently ordered 2 with the sight bowl and will be replacing the cat filter next time around.
