After reading the article on fuel cleanliness, I figured a better filter setup is necessary.

And others. The VW people run this filter as well. The VW TDIs use a VP30 pump, which is the small cousin of the VP44.

I plan to mount this filter between my stock filter and the CP3.

The Cat cartridge is crossable to other brands (Fleetguard, etc.) but I haven't figured out if they are the same efficiency. This filter can also be purchased with a water drain on the bottom, but I figure it isn't needed because the stock filter housing already has a water knock out on it.

Between the Walbro, this filter and the CP3 bypass, I figure I can make my CP3 live forever.

The filter head can be purchased from Cat directly or from other sources.

I am going to abstain from discussing this for a few days.

 

I have that CAT 2 micron on my old 86 F250, 6.9 .
WIX 33674

Plumbed before that I have a Fleetguard FS 1000 water seperator, WIX 33406

I prefer to have the water seperator with larger Micron rating before the 2 micron. You can also get a hand priming pump for the CAT 2 micron head, from CAT, expensive though.
A lot of DMAX guys run the 2 micron.

 

I have been thinking of doing the same thing but with the Stanadyne FM 100 between the OEM and CP3. My biggest undecided is where to manage fuel pressure at. Ideally, I would like to have two sensors wired through a toggle to the same FP gauge. However, should we manage back pressure by placing the sensors pre-filter, or monitor post-filter? Either way, you will still see when your filter is plugging. Monitoring back pressure will help you keep pressure under control before something blows with an aftermarket high flow/high pressure lift pump, probably mounted near the fuel tank. Is my line of thinking way off here?

Heck, maybe even put another 30 micron FM 100 pre-lift pump? Probably not necessary at all.

 

I installed a perma-cool 2 micron fuel filter/water seperator by the tank on mine. Bought it from www.jegs.com for $36.

On my 93 truck I ran the Raycor 445 fuel filter with the ( is it the brown one) it was 3 or 5 micron. It worked very well still have it in the garage somewhere?l Most told me to use the 30 micron in the winter but never had a problem with gelling at -40*C.Guess it was just a better truck.

 

I have a similar setup, not quite as pretty:

 

I run a 3 micron Baldwin Filter on my FASS. It's on their approved list and does not restrict my fuel flow... even when dynoing or drag racing! I'm sure the 2 micron would work well also...at least for daily driving.

After hearing about the Nicktane version of the Cat Filter set-up, I installed that filter on my '03 Dodge. It's been on for about 10 months, now and has worked flawlessly.
A couple of years ago, I had a Dually Depot, 115 gal. aux. fuel tank installed in the bed of my truck, in Elkhart, IN. To maintain Dually's tank warranty, you had to have a Fleetguard FS 1212 fuel filter installed, also. The FS 1212 is a pretty good sized filter (6-3/4" long).

After hearing about the Cat # 1R-0749 (Long Filter, 10-1/2" long) & doing some research regarding the fitment of the Cat filter on the FS 1212's mount, I found that they were compatible.

If anyone is interested, the filter mount is a Fleetguard product, part# 3930618-S & is priced at $29.81, at Cummins Rocky Mtn. They have to order it & it could take 7-10 days.

The thing that concerns me is that, the aux. tank is the only tank benefitting from the finer filtration. The stock tank is still only getting the 10 mic. Fleetguard (stock, factory filter) filtration.

There is an electronic valve that controls which tank the engine is receiving fuel from & I was thinking of buying another filter mounting head & placing it between the tanks & valve and the engine. This way, both tanks would benefit from the finer filtration of the Cat filter. I thought I would replace the FS 1212 where it originally was & move the Cat filter onto the frame of the truck, between the tanks & the engine. The FS1212 was mounted right next to the aux. tank.

SUPERDUTY, maybe you can answer this question, please?
Would running the fuel through the FS 1212, then the Cat 2 mic. & , finally, the stock OEM filter create too much of a restriction on the stock lift pump?

I have a Van Aaken C-3.2 (duration-only) box for added power & have not noticed any indications of fuel pressure loss, to this point.

Any thoughts from Superduty, or anyone else, for that matter, would be appreciated.

I hope the information I have contributed may be helpful to, at least, some of you.

Pictures please !

Excellent work.

I dunno. It isn't going to make its job easier. You'd have to measure some pressures and flows to be sure. I'm not a fan of the stock lift pumps.


I was working on finding a suitable filter head for the Cat filter on the weekend. The Cat filter uses 1" x 14TPI straight thread for the nipple. The standard 3/4" hydraulic filter heads are 1.050" x 14 TPI NPT taper thread. And they are missing an O Ring on the nipple because it is NPT.

You just saved me some work. Thanks.

 

Ha ! I found another filter head for the Cat 1R-750 filter.

Donaldson P174769. Should be about $24.

So... $24 filter head + $12 filter = $36 for a 2 micron filter setup. Inlet and outlet on that head are 1/2" NPT. I'll need to make a mount for it on the side of the engine and plumb it in.

Pictures, Buffalo... we need some pictures !

 

SUPERDUTY,

Due to the fact that I'm "technologically challenged" & have a "ten cent" computer, not to mention that I do not own a digital camera, I will be unable to provide pictures, for you. However, I can explain what the system looks like. It's really simple.

Basically, the filter mount (head) is mounted to the bedrail in the truck, next to the aux. fuel tank. The bracket is just a piece of "L-shaped" angle iron with holes in it.

The fuel line goes in one side of the filter mount & out on the other side.

Hope this helps.

Where were you able to find the Cat filter for $12.00? That's a heck of a deal!!! I paid a bit over $17.00, for mine.

SUPERDUTY, I just wanted to thank you for all your informative posts. You do a lot of research & development & generously share your findings with all of us. I have benefitted from your posts & appreciate your efforts. Thank You, again. I'm glad to have been able to provide you with some helpful information.

Thanks.

"Where were you able to find the Cat filter for $12.00? That's a heck of a deal!!! I paid a bit over $17.00, for mine."

At a Cat dealer. That was just the price. I bought it on Saturday morning from the HD truck service desk. Did you get charged RV pricing or something ?

Thanks for posting your part number. I've wanted to do this since summer and couldn't find a filter or a head. I found the Cat filter on the Duramax site. To find the Donaldson head, I crossed the number you gave. They wanted $125 for the kits on the Duramax site.

 

RJohnson! What is the filter number for the Baldwin Filter?
The numbers I got with my Fass say's the are 20 and 10 micron.

 

My Lit. from DPP said that also.. but it's a mis-print. The 3 micron is same as Baldwin 10 micron... with the suffix MPG, I believe.
Will go out and check it when I get a chance....
Stand By.....

2:43PM - 3 Micron = BT-372 MPG

I just picked up the parts to mount my Cat filter. It is going right underneath the air intake horn. Do you Dodge buys have enough room to mount yours there too ?
