true, but those fleetguard/cat cross ref numbers are for 2µ filters

both are good, get which is easier/cheaper to get



When I talked to a Cummins dealer (parts man), I was told by him that he had just talked to Fleetguard today, and he was told that the Fleetguard filter #FF5320 ( that is being sold, and touted as being a 2 micron filter, by a TDR advertiser) is "not" a 2 micron, but "is" a 5 micron filter. Which is still good filtration! Also, in my understanding, "which is very little" , That might mean that it is a 2 micron non absolute, but a 5 micron absolute. Sure is hard to know who & what to believe nowadays. I am sure I will get flamed for this :-{} , but at least we will probably learn more from it.

I've heard that same thing somewhere else too... but the filter clearly says right on it "For 2 micron applications", whatever that means. Even if it is only 5 micron at least it is getting it to Bosch's recommendations.
 
Here is a link to the Caterpillar fuel filter brochure. (You'll need Adobe to view it. ) On the 3rd page it gives the part numbers for some of their "2 micron absolute" filters. For those who use Fleetguard, the equivalent filter for the 1R-0749 Cat is the Fleetguard FF5319



The Cat 1R-0750 is the same as the 1R-0749 only shorter (about 7" vs 11")(Fleetguard#FF5320)



This info is from fleetguard however they DO NOT list how many "micron" their filters are. (guess it's a secret)

if any one is interested, i have the 2 programs [on pg4 of above link] for the eui and heui stashed away somewhere. it is a pretty simple quick crash course on those 2 systems cat has. i could upload it somewhere for others to download [most likely a torrent server]

both the fleetguard 5320 & 5319 have ( 2 micron application,high efficancy ) stencilled right on the side of the filter below the fleetguard logo. The ff5319 is larger capacity and will fit the GDP installtion and is also cheaper then the 5320. $11. 00 at the local Kennworth dealer.
 
2 micron filter

Which filter has the least flow restriction? Longer filter usually means more parallel paths and less restriction. Media type may influence that also. How are the Baldwin filters? For Wix try fleetfilter, they have the 33674, 9. 5" long, for $9. 17 plus shipping. Good prices on all WIX/ NAPA Gold. They also sell a filter head, under miscellaneous, for around $15, different than Fleetguard head which can be bought at Cummins for < $20. I am in Minnesota so combo factory LP and cold fuel means pressure drop/ less flow. Someone mentioned heated filter head, will that work with tank full of cold fuel at high flow > 1 gpm?



Someone needs to do a flow test to recommend the best filters for those of us who don't want to add the Walbro, etc. , and live in cold climates. Down south it may not matter as much but I would still want maximum flow. Since I've read in recent TDR magazine that high flow is required for cooling injectors wouldn't a cold ambient/ cold fuel mean less flow required? We may be just fine adding the honking 2 micron to factory setup.

The larger filter offers more media surface area and therefore more potential pathways for the fuel to travel... just like adding pleats to the filter.

I wouldn't worry too much about flow. The 0749 is the final filter on the C15 (14. 6 and also 15. 2L engines) along with others I'm sure. I would assume the larger displacement engine would require more fuel flow than the 5. 9 in most street applications.



I have a feeling the size of the fuel line would cause more restriction than the filter (clean of course).
 
I'm running the Cat0749. Big sucker. Have in mounted inside my truck tool box. Kinda backwards but don't have the room in the engine compartment to mount it post stock filter. Plus it'll make changing it out a breeze... :)

I can't help but wonder what will happen with all these auxiliary filter systems when the temperature goes down to, say 10 degrees. Probably not a problem in California though. If you do see some cold temps please do post up how the 2 mic filter with the stock lift pump performs. :cool:

I can't speak to the stock lift pump as I have a Walbro. I also have a 2-micron filter mounted back by the fuel tank. While I was in Indiana this past week during a cold snap, I started up my truck one morning when it was almost 0-degrees. No problem, and my fuel pressure gauge showed only a slightly higher reading of 25psi than the normal 22psi.

However, I highly recommend using anti-gel additives or you could have problems. I don't trust the fuel distributors to put enough in the winter-blend, and adding a little more doesn't hurt.

This is my second winter with my system. Yesterday morning it was 12 degrees out and everything was fine. In my opinion, the key is to retain the stock fuel heater upstream of the 2-micron filter.



Nevertheless, I don't think I've heard of anyone who didn't retain the stock fuel heater having a freezing problem with the 2-micron filters.

More on flow/ restriction

I don't think engine size has anything to do with flow requirements. It is more to do with what the flow is for. Cummins requires high flow for cooling injectors, according to last TDR magazine, not just hp. More so than the Duramax that is why they don't need a lift pump. I already know about restrictions etc. , Dodge has more. We don't burn 60 GPH most goes back to tank. That is why I mentioned least restriction to maintain flow with marginal factory setup. Please correct me if I am wrong. These replies have been great and I feel much better in installing 2 micron between CP and factory filter. When I get it setup I will measure flow. I am also interested in whether 10 micron factory has less restriction than 7 micron. Warranty may come into play there though.
 
Well, I recently posted on another forum about my recent problem. After a cold snap of single digits overnight lows, I was driving and started to notice my fuel pressure dropping. Normal 20psi became 17 then 15, 12, 5..... 2... eeeckkk :{



Made it home with 2psi. I think I was looking at my fuel pressure more than the road. Still drove fine, but had me worried. I hadn't used anything in my fuel for about 60 gallons or so of fillups... . Never again will I do that in cold weather, but it caught me off guard and I was very busy working. Definitely a gelling problem. Took my wifes ride to the auto parts store, bought some 911 and poured double the recommended amount into 7/8's of a full tank. Let the truck sit with the key on (fuel pump running) for about half and hour and she got back to 15psi. After driving (recharging batts) she's now back to 20-25psi cruise. I have 3 fuel filters and that may have been a precursor to my problem, along with some water in my fuel possibly. I only fillup at large truckstops, but who knows... :eek:
 
THIS is what I use for the transfer flow filter between my in-bed tank and the main tank - wonder if one of the 2 micron canisters will fit this type head...

I think the head piece is a pretty common cast aluminum job - I'll have to get the actual # off the filter and see what cross references to it...

I recently got over 2 quarts of water from a flying J... how big the truck stop is don't mean jack...

Buyer Beware

Just opened a box of 7 micron fuel filters I ordered in May. They were sold as Fleetguard. However there weren't any Fleetguard markings on the filter which came wrapped in celophane. The part number shown on the top of the filter was FS19800E. One would think that this stood for Fleetguard Stratopore 19800E.



Well, when I took out my old filter, it was an order of magnitude more robust.

The pleats were bedded in a heavy elastomer with a flange around both ends. THIS filter was clearly marked with a molded in logo from Fleetguard.

The "improved 7 micron filter", had the pleats glued to each end and used flat ends vs. flanged ends. There was no indication of any reference to Fleetguard.



I am sorry to advise you all that these inferior looking fuel filters were bought from Geno's Garage. I have never been disappointed by their products before, but I will never buy filters from Geno's again. So be careful who you trust to provide you with the best protection you can get for your expensive CTD.

I have some bad news for you. The filters you got are correct, and they do seem to be of inferior quality to the older 10-micron filters. We've heard this same report from a number of other people. Based on this, I'm thinking about getting more FS19579's rather than "upgrading" to the FS19800E.



Ryan
 
Thats good a thing eh? Upgrade the filter with a crappier filter. I think I might go back to the 10 micron since I have a secondary 2 micron now.

good luck finding them... if you can find fs19579's, you are getting new old stock. . it has been superceeded [or so cummins told me] by fs19579E. . thin plastic ends, with filter media glued to them. . i tried ordering the non E ones, but they are/were not avalable, so i have a box of fs19579e's sitting at home. they will work just as well, and the treehugger in you can be proud to help the envrioment:-laf:-laf:-laf
