NEW 7 Micron Fuel Filter

[HEMI®Dart]

Not sure if this is old news or not.



Cummins Filtration p/n FS19800E '03-'06 Trucks.



It looks like the '07's are going back to the spin-on's (p/n FS43252)

What kind of filtration does the old one have? 10 Microns?

i believe so...

 

[24V-DSL]

Page 15 of TDR issue 52 states that this filter would fit back to 2000 model year. It shows that it replaces the FS 19579 which is the one I use in my 01, and it is a 10 micron.



So, this reference to 03-06 trucks is confusing. Cummins NW didn't have them in stock, but have ordered them for me. Guess I'll just have to wait and see what's in the box.

arrrrrrrrrrrrrrrrrrrrrrrrrgggg



i just ordered 6 19579's



in general are the fuel filtration requirements of the 3rd gens greater than the 2nd gens



in other words; since i'm running stage 4 jammers in my '01 could i just use the 19579s in the '01 and order a few of the 7 micron filters for the '03?



or are the filtration requirements for the vp systems just as "tight" as the common rail ?



if so then just use up what i've got and next go round buy all 7 micron?

This new 7 micron is a push from Bosch , they told Cummins they really wanted to see a 5 micron but settled on the 7. I think because of the crappy lift pump situation

 

[AMassaro]

Just run a 2 micron after the stock canister filter and it'll be good. I don't think you can over-filter the fuel on these 3rd gens. JMHO

Fuel Filter-7 micron

Just checked with our local Cummins store and they do not have the 7 micron filter but will order several cases after I told him about them.

The new 7 micron is available from Geno's. Yes it was a compromise. According to the info I have read the new ultra low sulfur fuel is very very good at cleaning, so much so that it is cleaning diesel tanks, lines and pumps from the distributors right down to the gas stations. If you look closely at the fuel filler nozzle you will see a brown buildup on the aluminum. This coats everythng in the delivery system and that is what the 7 micron filter is trying to help keep out of you fuel system.

I just changed mine a couple of months ago, and won't be due for about a year or so. I wonder if it would be a good idea to get the new one BEFORE all this trash gets into my system. Also, it seems like it might be a good idea to change more often for a while till the supply line gets cleaned out. What say you.

I'd say 'yes' to both points!

Oil companies are currently delivering low sulfur to a few states (California being one of them). I have not seen any extra residue on my filters.

It would depend on how long the fuel supply equipment has been in service, We are getting some of the Ultra low sulfur and our above ground storage tank filters are plugging up very quickly. We are using 5 micron water absorbant filters and the tanks are 14 years old.

My case of 6 FS19800E filters arrived today.



Compared to the FS 19579 they look "cheap", and if I didn't know it was supposed to be a 7 micron vs. the 10 micron, I would have chosen the FS19579 on looks alone. They have greatly reduced the amount of plastic in the ends, and I was concerned it wouldn't hold on the canister lid.



Installed one, and it's all fine. Traded in my FS 19579's. The new filters were $12. 60 each.



So, if you have a 2nd gen truck and can use the 19579, this filter will work.

 

[MChildress]

The lift pumps are already a weak link,will these lower micron filters put more resistance on our pumps?

Hmmm... that bothers me.



I still have 4 or 5 FS19579's left, so it'll be 45k miles before I switch over. But then, the whole reason I built a fuel system was to provide 2-micron filtration, so I suppose it doesn't make much difference what I run in the stock canister.

Ryan...



I think the filter is fine. Sure can't tell it's 7 vs. 10 just be looking at the filter media, tho.



I'm concerned about reports that the ultra low sulfur fuel already available in some states has a detergent effect and may more quickly dirty any filter, so when it hits Oregon I'm going to check the condition of my filter every 2K rather than wait my normal 10K for awhile.

IS the low sulfur considered any under 500 whatevers per a gallon or less?



Cause I just filled p today in MO at Shell - and the pump had a sulfur warning on it...

 

[wcjp]

I noticed the older filter has a plastic indentation on the end. The new 7 micron filter has no indent. Haven't changed the fuel filter on my 06' yet. Does the lack of an indent make a difference?



The counterman at Cummins NW thought I was crazy until I presented the part number. No current plans to carry it locally.

 

[24V-DSL]

Tomeygun...



don't know much about low sulfur, but I heard it will go from 500ppm to ~15ppm



wcjp... The lack of indentation doesn't make any difference that I can see. When you pull your canister lid, you'll see what I mean. But, that's part of what I was complaining about with the previous "cheap" comment.
