Installing additional fuel filters, GDP w/ Cat 2 Micron, and a Fuel/Water Sep....

**AH64ID** · 07-23-2008, 05:39 PM

I have been wanting more fuel filtration for a while now. I finally decided to go with a GDP kit underhood for the 2 micron filtration and will add a BF1212 fuel/water sep between the tank and the OE filter bowl soon.

I am using a mostly GDP MK-2 + Big Line kit. I opted not to use the supplied fleetguard, or fleetguard filter base. I wanted to use the Cat 2 Micron filter and already had a Baldwin Filter base. Otherwise the kit is GDP. I am very impressed with this kit, all the fittings and parts are top quality, not to mention they will certainly reduce restriction.

Here is the intake horn pre install.

Here is the GDP kit, with all my additions.

Here is the assembled filter base and mount.

The new fitting in the CP3

The new fitting in the Fuel Filter Bowl.

The mount on the intake horn.

And the final install...

I also changed the OE filter today. I am going to continue to use the Baldwin PF7977 in the OE location. It has excellent ratings for dirt and water removal.

In order to prime the new system and to clean out the rubber line I left the line disconnected from the CP3 and bump the starter and let the fuel pump run until fuel came out the hose. The OEM In-Tank lift pump may not have the most pressure.. but WOW it moves some volume. After this it started on the first crank.

I am just waiting on the local machine shop to cut me a piece of steel for my bracket to mount the BF1212, then it will go on. I am hoping to install in on Sunday. I will update with pics then.

So in the end I will have a 20 micron fuel/water sep rated for 90%+ free and emulsified water removal, a 5 micron OE fuel/water sep rated for 90%+ free and emulsified water removal, and a 2 micron fuel filter.

Good call with the Cat filter, I love mine. Install looks great!:thumbsup

Thanks, yeah after getting the run around with Baldwin I went back to my original plan.

I got some free time and got the Baldwin Fuel/Water sep on today.

I had a bracket made that bolted to the bottom of the back bolts for the front seat. I had to replace the OE bolts with ones that had more thread. I then bolted the Baldwin filter base (FB1311) to the bracket and ran the plumbing. I used 3/8 compression fittings on the OEM steel line. Everything went together real smooth. I did have to take the NPT fittings from the compression fitting to the push-lok apart and reseal with thread seal tape due to a small fuel leak. But all is well now. 3/8" hose and all the fittings are 1/4 NPT or -6 JIC.

and its tucked up neatly above the xcase skid plate and the frame.

And a closeup of the fittings.

Update: All is going well. I have more than 6K, 200 hours, and 350 gallons thru the setup without a hitch... I am hoping to get a fuel psi gauge in the next few months, but we will see... I am going to plan on 20K change intervals until I get a gauge.

Wow thats a nice set up..

So with your stock fuel pump it seems that you have no problems getting fuel to the engine through all the filters right...

Also how much does the cat filter cost you??

I have not had any issues yet. My dad has a similar setup that was installed by a dodge dealership. They say there have been no issues on the 05+ with the in tank LP's.

The cat filter is $14.xx at the local cat shop.

I have done some dyno's before and after the filters. Even on SW#3 on my Smarty Jr there wasn't a noticiable difference in power. So I don't think I am fuel starving the engine. One thing that helps is the big line kit. It increases the flow from the OE canister to the CP3. According to GDP flow is better with the big line kit and filter and stock.

That sounds pretty good..

It sounds like you dont like fleetguard.. Or is the cat filter much better..

**AH64ID** · 11-13-2008, 08:23 PM

The cat filter is a true 2 micron, the fleetguard is really a 5 micron... And for the f/w sep the baldwin and fleetguard are about the same and since its my first of 3 filters I used the cheaper one.

my cummins dealer was cheaper than the Cat place for the cat filter.

i think i paid 13, cat place was like 19 or 21.
