AirDog filters

[dougs455]

I have been using fleetguard filter # FF5613, which is either a 3 or 5 micron filter can't remember off-hand.

"Word of mouth" size... . so not sure.



Yeah, call em or email for us will ya?

 

[HeavyHauler]

We'll do. I'm tyring to decide how many of these things to order. I've got a FP gauge in addition to the AirDog "dummy" light, so I guess I'll start changing fuel filters based on pressure to the VP44. The manual says to change filters when the light stays on, but the AirDog light will only come on if the FP is 7psi or below, and that's a little lower than I would like to run.



What are you guys doing about filter changes? I've been running my current filter for around 7,000 miles with no pressure drop to speak of. I'm thinking these things may be good for 20,000 - 25,000 miles depending on the quality of fuel. I'm thinking about changing when pressure drops below 14psi at idle.



Any thoughts?

 

[dougs455]

My filters are @ 10k with no drop in pressure with 16psi @WOT. I too would like to change them but cant decide which filters to use. Are the 2 filters different or can I use 2 FF5613's?

 

[BDR]

So how come my pressure seems to be lower? I'm at around 13. 5-14 psi. Is it year dependent on psi differences? Any ideas or opinions fellas?

I just changed my filter at 20k, but the fuel pressure still had not dropped at all from when it was new, so I believe the filter is good for at least 25k provided the fuel is of good quality. dougs455: the second filter is the water separator and should not need to be replaced unless it is damaged (this according to the airdog users manual); I don't have the fleetguard part # for it currently, but should be able to find out soon and will post it as soon as I have it.

Airdog is the big dog and the top dog!



Have 110,00 mi on my Airdog. Love it! Absolutely no issues.



First filter change was a spare Airdog filter at 30,000 mi. The VP was dying and I installed the Blue Chip FedEx VP and my fuel pressure instantly dropped! The original VP (400,000 mi!) was not pushing much fuel. After filter change the pressure was back to the normal 19. 5 lbs even with the Catcher installed. Just changed the filter again last week after 70,000 mi, psi was just starting to drop. This time I installed an FF5613.



The micron ratings per Fleetguard are as follows:

FF5613 5microns absolute

FF5587 7microns absolute, 5microns 88%

FF5617 10microns absolute, 5microns 83%

Sorry, don't know the smaller micron value of the FF5613.



To buy the filters and water separators pm 78repowerwagon.

Guys,



78repowerwagon is currently not a TDR member so pm me if you are interested in filters and water seperators for the AirDog or to purchase an AirDog.



TIA

I finally got around to installing a fleetguard replacement filter. I am using the FF5613. Thay were $28. 22 for a 3 pack at the local international truck dealership. A few interesting pics.



Matching stamped #'s on the filters.

I'm not sure about the #'s on the last pic. I can tell you that the ff5613 fits perfect and was less than $9 for a 5 micron filter.

Love my Airdog,just changed my fuel filter (5617) for winter use and then go back to the 5613 over summer. Last winter with the stock Airdog filter(5 micron rating) i had some pressure fluctuations in some fairly cold weather with lots of fuel additive. I though maybe up here that running the 5613(5micron rating) might be a little to much filtering with the winter blended fuel. I'll try this for now and see how this winter goes,its not uncommon to see -30/-40 belowC in Dec/Jan/Feb. Filters from Cummins in Calgary-5613(14. 38),5617(13. 56)CAN$$$. Later DW

so that airdog has a 7/8"-14 thread eh...



there are 3 different cat high efficency 2u fuel filters that have that thread. . maybe they will work? [if the gasket lines up ok]



cat# 1r0751 - fleetguard# ff5321

cat# 1r0753 - fleetguard# ff5322

cat# 1r0759 - fleetguard# ff5324

 

[HeavyHauler]

It looks like those CAT filters that you mentioned have a smaller diameter gasket on them. The gasket on the AirDog filters go to the rim of the can (as shown above) where the CAT filters look to have at least 1/4" between the outer edge of the gasket and the edge of the can.



I'm basing this on pictures of the Baldwin equivalent of the CAT filter. Here's the picture of the Baldwin BF7632 (CAT 1R0751).

true, but the ff5613 lists at 3. 05" OD, ans the ff5332 lists at 3. 68" OD



so the cat spec filter is a little larger in OD, but the gasket might line up properly. . and from the pictures of the filter head, there should be enough room for that extra bit between the filter and separator. .

 

[HeavyHauler]

I guess anything's possible, but I don't see the point of taking a chance when there are 3 different Fleetguard filters that perfectly fit the AirDog.



I'll commend your research though - I'm always interested in having other options.

DWeiler - I have noticed some fuel pressure fluctuations with my AirDog as well. I'm also using the stock AirDog filter which has been on for over a year with the FP still staying above 16-17psi.



I was under the impression that the stock filter was a 10 micron, but apparently this is wrong? For whatever reason, my fuel pressure will hold a steady 17psi when I am running waste engine oil with my fuel, but I have noticed it fluctuating 2-3 psi lately since I haven't run any engine oil.



It will swing all the way from 16psi to 19. 5psi every now and then. Mostly it just swings from 17-19psi when it does fluctuate.



Do you think going to a 7 or 10 micron filter might help?

Probable not,even from day 1 with the stock and this summer with the 5613 mine moves from 16/18 most of the time,give or take a 1/2 psi. From what i was told from the place that i bought it from was that "the filter was a 5 micron rating". I might have to call Pureflow to find out more on that. My fuel pressure will still drop 1-2 psi, more when it is hot outside---25/ 30degress outside temp,but that is probable from the warm fuel in the line/guage getting heated up in the sun on the "pillar". Once i drive for a bit it starts to rise back to normal but it still moves abit---i guess the fuel finally cools(and YES i know its not good to run fuel into the cab but this is the way for now ). I seem to have a bit more stable fuel pressure now with the cooler temps(fall)now. Last year when i noticed the drop in pressure,the guage was moving back and forth about 5psi and then would be ok for a bit and would do it again. This was in really cold weather,I didn't like it,it seemed like i was driving with my eye on the guage all the time waiting for 0 pressure. Once the cold temps went away it stopped doing it. Maybe it was starting to gel up,beats me,but another guy i talked to said that they were having some problems with the "Airdog stock filter" in really cold weather too. He suggested to run the Fleetguard 5613 for summer and the 5617 in winter. This will be the first winter i'm running the 5617 so time will tell or i'm blowing smoke up something :-laf . PS--- I ran into a guy with a DMAX and Airdog who works way up north(Fort Mac/NWT)never has had a problem,lets it idle all day/night while working as a welder---stock filters never had any gelling/problems and the DMAX looked like it was run hard---pretty beat up but the AIRDOG hung in there.

One has to be creative sometimes. The AirDog setup does not allow enough room for most 2 micron filters with 7/8" 14 thread. If one of the Cat filters fits it would be a small victory of sorts. If the Cat filter will fit in the confined diameter allowed by the AirDog and provide 2 micron filtering I would buy you all a beer. You have to come to Utah for it of course.

I'm open to more options,

 

[dougs455]

I'm gonna stay with the 5613 unless airdog sends me some free filters. 5 microns is plenty enough for me as thats what the factory filter is rated at. Lat year in the cold the factory filter with 15k miles stranded me at work due to gelling at about 0 degrees. Thats with stanadyne in #2 fuel. It would idle @16 lbs. but any throttle would drop it to zero. If it freezes again I may try the bigger micron filter like a 5617.

Hey DWeiler,

I'm in Calgary all the time on business.



I just finished doing the Vulcan 'draw tube' conversion to feed the AirDog. The factory fuel module has some very fine silk screen that is removed during the Vulcan update... . perhaps you know about this so I won't bore you.

None the less my entire fuel delivery system is modified and The only thing left is 'cold service' trouble prevention.



I called Maesco yesterday to check on the Racor fuel heaters. The price isn't cheap but the device is way cool. Gelling-up would never be an issue if warmed diesel is fed to the AirDog at idle for a few minuets... . at 65 Amps I think you could go -40 if it's plumped into the feed with short lines. As for getting DC back to the unit... . it won't be cheap either.



www.maesco.com

Click on the Racor products and slide down the page to the fuel heaters.



I think you might like this little tool. They have in-cab controls and thermo control on the unit so it will turn it's self off if we forget.



BTW... guys... thanks for the research on the Fleetgaurd fuel filters. I'm in the market to get a couple units.

Thanks for the info WTBURKE,hope you enjoy your stay in this fine country/province"EH". This city is getting crazy with the super heated economy now,115+ cars are being added to the steets everyday as people flock here for the "So-called Alberta Advantage",inflation at its highest in years. Good side is my house has tripled in price so i may/want to sell it and move to some small town and live off the profits . Who knows? Yes i have heard/read up on the 'Racor"options as well,and definetly are pricey. Right now i'm just going to try to see how the lower micron rated filter does this winter,if it works i'll stick with that. As well i still have my stock full heater hooked up with the 'Airdog" plumbed into it so the fuel is getting heat in the winter months. Thanks again for the suggestions ----LATER DW
