2 Mic FF or H2O Sep?

In the above post, I settled my lift pump issues for the time being. Now I'm trying to decide whether I would be better off running a water separator before the stock fuel filter or running a secondary filter such as the 1R0730 between the stock canister and CP3.

I'm leaning towards using a 2nd Gen 10 micron element in the stock housing and using a Fleetgaurd FF5320 between it and the CP3. My thought is that the stock water separation is pretty good and adding the extra filter after the stock canister means the fuel has already been warmed some by the fuel heater as well as the mounting location next to the engine allows for some additional heat.

Now for the really "loaded" question...opinions? I know this has been discussed at length, but I'm not sure I've ever seen it asked as an either/or question.

Why not use a 5-micron Baldwin BF-7977 in the canister and than step down to the FF-5320 or as I suggested before the Donaldson P551313? I know cost, but those injectors negate any price considerations when it comes to filters.

I understand your perspective, but mainly the answer I was looking for is that finer filtration is more important than extra water separation. I like the idea of using multiple steps in filtration in order to keep restriction to a minimum, but I guess your perspective is that when you only have "single pass" let each filter have a chance to catch what it can in order to have a cleaner product in the end. I have a small concern about the flow of the stock filter (I have been using the 7 micron Fleetgaurd), but I suppose so long as I maintain positive fuel pressure to the CP3, it's really a moot point.

If you want the best filtration possible, both. Run the BF1212 back at the tank with a heater base and either a CAT 1r or the Donalson between the stock housing and the CP-3.

The BF1212 is a rock catcher but it is excellent with WS operations. The baldwin and Donalson past it will catch the solids. AH64ID is running those with a stock LP and unless really tune the engine up or run it hard the in-tank works fine. I run the Donaldson and Baldwin with no pressure issues unless I turn the wick up too far.

I can't argue with that. I'm using a Baldwin BF-1258 between my auxiliary and OEM tanks that is gravity fed. The Baldwin rep. told me that it is a jam-up separator as well as being a 9-micron absolute filter. Of course this is before my lift pump and I need to fill-up using only the auxiliary tank. I know for a fact that if you do use the OEM tank and don't get a good seal on the fuel cap, you'll have an expensive mess on your hands.

I noticed in a picture sometime back that Wayne posted that he had installed a pressure gauge on the outlet side of the GDP mount. I like that idea. At least you could track a pressure drop after establishing a baseline; and, without the aggravation of running a pressure gauge inside the cab, you would be able to at least monitor the condition of the filter.

Since I'm running a stock lift pump we're comparing apples and oranges to some degree because I realize you are wanting to monitor your pump as well as get good filtration. Put me in the column headed by Cerb - both.

Im taking my chances and feel pretty secure about my setup. The stock FG 7u filter and the FG spin on I made a post on. I have no issues in the months so far. And my summit gauge is holding up fine. I may switch to the baldwins but the jury is still out.

Cerb, can you post a link to a heated base? My climate isn't much different from yours, but I really don't want to ever have to worry about frozen/gelled fuel.

Cerb:
Does the FS 1242k come with wiring instructions that can be understood by someone with limited wiring skills or do you need to be an electrical guru to wire the unit?
thanks, steve whalen

I think the biggest challenge will be getting a trigger so it comes on the same time as the OE heater. This is a universal kit meant to wire into many platforms so would assume it should have decent instructions for getting it wired correctly. What it won't contain, likely, is the instructions to connecit to the OE harness. That should be relatively easy to do with a relay and tapping the correct wires on the engine. The Dodge Severe Duty filter taps in there so it can be done. AH64ID has one installed, I would ping him and see how it is wired so it could be copied.
