2 micron fuel filter?

[Diesel Power]

yea hopefully i will have something thats set in stone soon for all that see what we do.

As a former Duramax owner we went through all of this back in 2001-2002. Your best bet is to run a pre-filter that has a good rating. Check out www.kennedydiesel.com or www.nicktane.com.



I'm not talking big horspower applications here so I don't want to step on vendors toes. For big hp the added restriction without the pumps may not be a good thing.



Personally I ran the Racor in my Dmax as a pre-filter. Dmax has NO LIFT PUMP and I was able to pull fuel through this filter and the stock unit.

Ryan: Is your setup a return? Does it cycle fuel back to the tank like the FASS and Airdog??

It does cycle fuel back to the tank, but it uses the FCA rather than a separate regulator and return plumbing.

For those of you wanting to know about the FG hydraulic filters used in the FASS...



300psi working pressure, 35 GPM (not gph), b>200 = 12micron, b @ 75 = 10micron, b @ 2 = 3 micron... and if I read this right, that means it is greater than 99. 5% efficient at 12 micron, 98. 6% at 10micron, and 50% at 3 micron.



Or in theory, not much better than a stock filter, albeit, we are no where near it's rated capacity at 1. 6 gallons per minute.

maybe i read it wrong but it looks better than the 2 microns ratings, if you factor in the gph diference... ...

For the HF6604?? That's about the best filter (for filtration) you can get on the FASS...



The HF6607 is the next best FleetGuard from my research... but there are also others that are similar.



I was just spewing the ratings they had listed...





I will add that I don't know how to figure the micron efficiency for different flow rates...

your right the 6604 and the 6607 are the best so far, but down th eline i saw other much better rated filters that had the same head design, i will call them today and also i found good filters from donaldson absolut 3 microns that seem to fit what we need.

Which donaldson? The P169392 is a direct fit according to them... and equal to the HF6604/HF6607.

Shoot, I should have also said that the HF6600 series is 3. 67"D and the others are 5. 02"D... they wouldn't clear the brackets... which is a shame as the one is rated for 98% @ 2 or 3 micron... at still well over the flow rate we need... I'm considering running on of these just downstream of the FASS (and upstream of my guage) for added protection...

thats it. im trying to get ahold of some one, but it seems impossible :{

the newer fass units have a different bracket design that allows for a bigger bodied filter

 

[Diesel Power]

Oo. any one have a # for donaldson i cant find one at all. thanks

ok after a long but fruitful day i found what we need, the water fuel separator is fine, it will flow well over 200gph. but the other filter is the one we need to replace. i will have a part # and all as soon as i can get case quanities, im still looking for avalibility. Oo.

For some reason I never got notified of a reply to this thread...





What are the specs on the filter?



Will this be for the new FASS design or the older units? I assume it is a Donaldson?

it is from fleet guard, it flows 30gpm, so it meeks our gph spec, and its absolute 99. 5% @ 5 microns and 98. 7 @ 2 microns looks good Oo.

The Pressure will Kill the Rating... That"s the problem with High Volume Rates=Mic ratings.

todd, the filters are under suction which is different than pressure and the new filter is rated for 30+ gpm our pumps max out at 200gph and there rated @ 30 gpm, thats minute for those that dont catch it... ... :-laf

Dumb question... assuming a clean tank, wouldn't it be much simpler to just filter down to 1 or 2 microns when dispensing? Ok so I didn't have anything more intelligent to ask
