I noticed that Glacier no longer sells their dual filter set up. I have that on my 2005 Dodge 2500. Glacier has another single kit which uses a Fleetguard FF 5320 and is a 2 micron filter. The fuel is getting pushed from the engine mounted fuel pump that's mounted under front of engine. It has a small fan belt to pump for engine power. I mention this because I know you don't want a vacuum type for filtering, you want a pressurized line for fuel filtration. Seems to me that one filter had a water valve at bottom, but it's been so long that I don't remember.
