AH64ID,
The filters are Wix (or NAPA) 533407 for the water separator (it has a manual drain valve) and 3674 for a rather tall 3 micron final.
These are frame mounted on a set of bases I set up myself. I thought they were doing OK because I periodically open the original filter which is still mounted in it's original location and it stays clean as a whistle, with no sign of water. The Wix, or Napa (depending on which one the fleet supplier sent me), does collect water and needs to be drained occasionally but none of that ever gets through to the original Dodge filter.
The drain valve is plastic and I can see why that might concern someone. Guess I'll look for an alternate.
Thanks
Rog
