Cummins Cat Dual Fuel Filter Kit

http://www.cumminscatfuelfilter.com/



I ordered this today, ordered the dual filter kit. Was wondering what the general thoughts on this are. I have read various threads on the subject of filtration, from engine mounted to frame, to replacing the pump so that the water seperator is on the vacuum side, etc... . And while this one isnt, I still think it will be an added measure of protection over the stock filtration I currently have. Anyone see any major downfalls of this system?

I think it is a great way to start out with better filtration as I am using it with the stock intank pump . I will give you model #'s of the filters (we) the TDR group thought were the best way to go with if you would like. Follow the directions and don't over tighten the flex to steel lines.

thanks, I appreciate any info. My current thoughts on filters is to replace the baldwin F/W with a donaldson, simply because for me it will be cheaper and more readily available. The Cat filter will remain Cat as they will be free to me.

I feel that after installing the system and running it for a couple days, I will replace the factory filter with a fresh Fleetguard 7 micron replacement to remove any debris/contamination from the install process. After that, I will not replace it except on a yearly basis just out of guilt! I also feel that alternating the change interval will give me max protection against contamination from the filter change process. If the base assembly has provisions, I may build a differential pressue rail to monitor when its time to replace the filters.

Looks like a good kit, similar to the one I made for a single filter on my truck years ago.

Don't replace the Baldwin f/w sep with a Donaldson as they are only 85% of the emulsified f/w sep vs the 96% on the Baldwin.

The Donaldson P551313 is rated better than the 1R-0750, but the 1R-0750 is a better filter.

interesting about the baldwin vs donaldson f/w seperator. . I will have to see if my parts guy can get the baldwin then. Yeah, im definitely using the Cat filter as it is free! Thanks for the info!

Is there any concern that the stock canister mounted pump may be over taxed trying to pull through a 2 micron filter? We already know that the pump is a weak link in the system, will this setup make it worse?

 

[AH64ID]

The 2006 the OP has doesn't have a canister mounted pump, it's in-tank. Starting in 2005 all the pumps have been in-tank and can push thru 3 filters without issue.

my 06 model has the transfer pump mounted in the fuel tank. To date, I have not heard of anyone having a fuel delivery issue with the in-tank pump. I agree though, I would question the older engine mounted pumps ability to draw fuel thru the auxillary filters.

Yes, that is a concern with the engine mounted pump. Not so much with the tank mounted pump as they are capable of a lot more flow and pressure than the others. As long as the fueling curves are not drastically altered the in-tank pump will work fine. They run out ability when you go over about 450 HP though.

I bought this single filter kit with the full intention of putting on two filters. Since the dual filter kit didn't exist yet, the filter I chose wast the Donaldson P553203. It is a 3 micron filter and a water seperator. I could have put on the Donaldson P553207 which is longer and has more media for less restriction, but I have lost any power yet.
If I feel confident that stones won't hit the filter, I could add a clear bowl on the bottom P569758 so that I can see if I am getting any water in the system.

On a seperate note, if you use a fuel additive that has a demulsifier in it, I think any water in the system might pass through the filters.

I thought briefly about installing a Cat F/W seperator with polycarbonate bowl, but do not want to have issues with something hitting it. I am going to look at the protection I have once the system installed. It may be a valid option later.
I don't use any fuel additives, at one time, I would occasionally dose it with some Cat fuel conditioner, but not anymore, it will live on diesel or it will not live.

we have run dual filters on all of our cr's since 03. you can make a filter for $100 the 2 micron filter is a sub for a cat 1R0749
we mount the filters just forward of the fuel tank. we run a fleet of dodges and recently installed one on a 06. there is two bolts through the floor board for a rear seat option at this location. some of our trucks use them others do not. get a 2" x 3" piece of angle iron 6" long. make a card board template that the two bolts and keeper nuts will go through hold the template on the inside against the 2" part and drill the two holes they will be about 5/8" i think and about 3 7/8 " between. center the holes on the 2" and near the edge on the 2" hold the angle iron over the bolts with the 3"part the furtherest away from the tank and drill a 1/4" hole between the two holes, keep drilling through the floor board. now after you mount the filters to the angle iron just simply mount it with a 1/4 grade 8 bolt. this is the only hard part the other items is easy. the total time including building the bracket is about 1 1/2 hours. i will give you napa numbers but they can cross reference to wix or car quest. the two bases are 4770 the water separator pre filter is 3406 the 2 micron filter is 3674. use a 3/8" nipple with about 1/2" space in the middle connect the two bases together observing the in and out. because of this the mounting plate on one filter base is about 1" further out than the other. install two 90* 3/8" barbed fittings on the bases and temporary bolt the angle iron up and hold the filters up to it. make sure everything clears and mark the one base that touches the plate to drill the three holes to mount the filters. next cut the feed fuel line at this location and bend the lines out a little and install 3/8 hose over the lines and to the barbed fittings. i put a small amount of flair on the steel lines. but i do not think it is necessary. Bleed the air out through the stock filter before trying to start it. use a gauge and do not change the filters until you see a four pound drop this should be about every 150,000 miles and the stock filter will never need to be changed. Cheapest place is http://www.fleetfilter.com/filters/wix-filter-bases.html

your filter base has two inlets and two outlets on each base be careful to connect the nipple between the outlet of the first filter to the inlet of the second. only one of the bases get's the bolts as the offset places the second base about a inch away from the plate. we use to make spacers on the first ones and then decided they were not needed

There is no doubt that I could have built the same setup that I ordered. Looking at the parts in the kit, they are from a Cat dealership, so I could have gotten the same parts. But, sometimes its just easier to purchase something vs building it myself. The main thing I wanted was the bracket that has been fabricated to hold the dual filter base.
With the way my work schedule has been recently, I will barely have the time to install a pre-made kit let alone building one.

I bought the duel set up last night....looks like a good set up...saw it a while back on here, but forgot to get it....

Same here, someone originally posted about this kit with a single filter setup, i looked at it, but they had advertised a dual filter setup coming soon. I saved the link to the page and would check back every so often waiting on the dual filter setup to become available.
wish I didnt have to wait for USPS to deliver!. Ran my tracking # and they are saying maybe the end of next week!

With an auxiliary filter setup like this, is there any additional concern to fuel gelling in the winter? Do they make one with a heating element for colder environments or is it not something to worry about?

 

[p-Bar]

Fuel gels at 17.5 f .maybe think about a blanket that they use on backflow devices .

 

[AH64ID]

If the fuel is not properly treated the first exposed filter inline is generally where gelling occurs. Fleetguard does sell filter heads with heaters, and you can tap into the OEM heater to trip a relay (this is how mine is wired).

I also have insulation on my exposed filter to help keep the fuel in the filter warm.

AH64ID not to hijack thread but how is your rebuild coming along?

 

[AH64ID]

Slow and steady, should be out of the machine shop next week. AFIK all the parts, minus injectors, are here.
