So... ..... what can we do to come up with an improved filtering system?? Besides the AirDog... kinda costly.

 

[WCounts]

Dirty fuel

Your fuel system is worth the money spent on a high quality filtration and pusher pump system that also get the air out. These are easy to service and filter to 2 microns.

We knew that, Hammersley! I believe 2 micron (or better) filtration is the answer, and I'm doing exactly that here.

Filters ,3 micron zinga. This Pump is a 15 GPM ,the 3mic reduce it 6 GPM. I don"t think this filter will work on any bolt-on-application the reduction would be to great,the Pump could not support it.

and? How does this plumb into the stock system?

 

[nickleinonen]

there is a new lift pump setup coming from Racor that looks like it will be great... fuel/water separator and a separate 2 micron filter with brushless dc motor that is variable control to provide constent lift pump pressure with engine speed/load...



there is a 2 page spread on this racor lift pump/filter in the feb issue of diesel progress magazine [click here to subscribe to it for free]

Great post hammersley! I get asked severel times a week about fuel additives, My answer is always "Save the money you were going to spend on an additive & buy good fuel" Every body knows about the lube properties that diesel plays in the Injection pump, But fuel also in used to cool the pump. On 2 occasions we have been involved in insurance cases due to watery fuel. Both cases boiled down to someone leaving the top off of a underground fuel tank.

The Duramax guys have been fighting this fight since 2001. Ask Hoot, he can tell you all about it.

Our pressures are up from 17,000 with the P pump or 14,000 with VP44 to 23,000 (more with pressure boxes). Not a factor of ten, more like a factor of 2 at most. I believe the Fleetguard Stratapore stock fuel filter works to 2 microns. I think that was the point of the new design stock filter that came with the 1998. 5s with VP44, and retrofittable to 97-8 12 valves. I always used the better filter on my 97 and I think it has superceded the old one.

Some of us keep hammering away at the poor fuel quality issue - and I myself have posted many pics of both my frantz oil bypass, AND the Frantz SUB-micron fuel filter - there's even a thread on this board on the subject.



Here's an underhood shot showing my setup, with a Frantz filter on each side of the engine bay next to each battery:

We've been trying to point out that poor fuel is a major factor in VP-44 failures, and that ALL fuel pumps ARE affected, even the latest stuff, as revealed in the lead article. Some diesel truck owners soothe themselves into thinking that newer ultra-low sulphur diesel fuels due to hit the market will eliminate all fuel related failure issues - totally oblivious that NO fuel is any better than its refining, transport and storage. The new ULSD will be just as dirty and contaminated as the stuff we NOW are burning, regardless of sulphur content!

Where are the best places to get quality fuel?

Joe: I believe the Fleetguard Stratapore stock fuel filter works to 2 microns.

I did some snooping around and came across some threads of interest. What miffed me the most is the info wasn't readily available on Fleetguard's site, although they have a lot of info available.



Anyway from another forum:

http://www.dieseltruckresource.com/showthread/t-39961.html

They say the FS19579s are only 10u. (I figured I could use the u for the greek mu which is the micron symbol from my soil science days. This is sure to impress some of you... I think . If not, at least it impresses me that I actually remembered something from college :-laf )



However, on this site I found this:

04883963AB is a new 2 micron fuel filter element, which must be used with the Chrysler ISB application. The 2 micron filter replaced the 7 micron 04883963AA filter, which is no longer manufactured.



http://dodgeram.org/tech/dsl/Facts/98ISBspecs.html



Thus, it seems if we get the Mopar filters we get the 2u. Hopefully, someone else can dig up some appropriate info that suggest the Fleetguard stratopores are 2u.



That begs the next question. Is anybody running the Mopar 2u filters experiencing injector woes? I see the AirDogs are 3u. Is anyone running an AirDog and experiencing injector woes. PLEASE NOTE WITH OR WITHOUT FUELING BOXES.

 

[crobertson1]

OTD,



So, you're saying the Mopar filter in the factory setup is 2 micron filtration? That sounds good.

 

[rbattelle]

I asked Fleetguard specifically about our fuel filters, and here's their response:

Thank you for contacting Fleetguard.



The FS19579 is a 10 Micron at 98. 67% efficient.



If we can be of further assistance to you, please feel free to contact your Fleetguard Customer Assistance Center or send a message to FleetMaster.

Traildog, where did you get the info that the Mopar parts are 7 (or 2) micron? The stock filter that came out of my truck was identical to the Fleetguard model that went back in it. How efficient is the stock filter if it is at 2-micron? I mean, even a 10 micron filter will remove 2 micron particles... at pretty low efficiency.



Nick, I read the same article in Diesel Progress. But it seemed to me that it would be a monster, intended for large OTR trucks and probably very $$$.

I was impressed, I still use the u for micrograms/miligram eg. , ug/ml regognized right off. this is great info! Thanks.

Joe, any restrictions on retrofitting a '96 with the newer canister? I assume you're speaking of the '98. 5-'99 canister on your '97. What about the 2000+ canister? I think with rerouting a wiring harness and bolting to the rearmost position I could fit a '00-'02 canister on my '96.

PDR's FASS

Great info -



PDR installs 3 micron Cimtek filters on the FASS systems they sell - I took my original filter out of the stock canister when I installed it but am now thinking about reinstalling it at next oil change to get 'super clean' fuel.



Dodge specs 10 microns - I believe - I will have to research on this 2 micron statement for the stock filter.

[Ol'TrailDog]

Traildog, where did you get the info that the Mopar parts are 7 (or 2) micron? T

The info came off the dodgeram.org website at the bottom. Albeit, the information is for the fuel filters for the 98. 5-02 specs. I would assume (dangerous, I know) the same specs would apply for Mopar filters after 02. Since the site has something to do with Genos, maybe he knows for sure. Also, it doesn't seem reasonable that Mopar actually makes the filter, instead of someone making it for them.



Bottomline is there are still several questions haven't received DEFINATE answers, i. e. are the 03+ filters still 2u, who makes the filters, and is the info on Fleetguards correct, is there any correlation between injector woes and non-Mopar filters (excluding fueling boxes)?
