FASS or AirDog? - Duramax Lift Pump Install

2001-2010 Duramax truck were not equipped with a Diesel Lift Pump. This video will help you understand how that creates engine performance issues in your truck and how to install a Fass Lift Pump to eliminate those issues. The FASS and AirDog installation process is only slight different, and I will show those differences, and help you understand the pros and cons of each.

Ive got an Air Dog sat on my dinning table, I’m starring at it and the the wife and kid are starring at me. None of us were happy, until we watched your video… wife said “well, I suppose you can do it and we will get our @#^%ing dinning table back then”. My daughter said “daddy can I help”..? So thanks for making a video that makes it look fun for my kid…… she’s probably just going to bring me some snacks and ask me to play Mario Cart, but she’s 9, so I’m flattered 😊

[@freedomworx]

She can help you find the 10mm when you lose it 😂

[@ondago2]

Man take that love and that experience If a kid wants to help and especially a daughter I had one and she ended up going to engineering school following in my footsteps but if she wants to be there and said she if she's going to get snacks and ass to pay Mario kart or get a wrench or get you a drink or whatever dude enjoy it cherish it man.

[@FASSFuelSystems]

We appreciate your business, and hope you love the system!

[@freedomworx]

Thank you much. 👍. It’s doing its job thus far. 👌

[@ondago2]

You didn't make this video until a few months after I had installed my first ever lift pump I ever seen even first diesel truck but I got to say in retrospect I think yours is the best of the videos that I've seen. First off besides being thorough about what to do and why you injected some humor and fun and it made it actually cool to watch through even though I've now, done it.

[@freedomworx]

Sorry it didn't help you, but i'm glad you liked it 👍

[@tom58792]

Baldwin filters are very good.I used them on the ranch for 20 years

[@freedomworx]

Yep. They make good stuff.

[@paveltolz6601]

I've had the AirDog 165 II on my 96 GM 6.5L since 2013. The truck is happier with it than the OEM. Even the OEM 1994 LP which was supposedly a little better. Mine was gifted having been on two previous trucks since 2008. Customer service was great as I chose to go with new hoses vs. the already twice cobble up ones I recieved. Clear instructions and I'm not intuitive though I had to adapt because at the time, there wasn't a kit for the 6.5 motor equipped trucks (They do now). The pump motor failed after four years later (guess I'm part of another 1% group [Veteran) and, again, customer service was great. Sold me a new motor only and for a low price and I was able to repair the system in short order. The truck was off line until last year and I just reinstalled the AirDog. Again, the truck is much happier and I plan to leave it in.

[@freedomworx]

Sounds like AirDog takes care of their people 👍

[@rbyronson2426]

I’m still in the process of saving my money to get 1. And thanks again for the laughs throughout the video.

[@freedomworx]

I appreciate you watching 👍

[@johnnyfever2]

great video! i ordered a FASS pump today and plan on following your procedures! your video is the best procedure ive seen on youtube! my 2008 w/160k is having fuel issues possibly due to vacuum loss from worn seals hoses etc. i agree completely with the need for a lift pump for the high pressure pump feed. makes perfect sense as many diesels have! not sure why duramax didnt use lift pumps on some systems! thanks for this great install video and helpful and interesting information.

[@freedomworx]

I’m glad you enjoyed it. Hope it makes it go quicker for you than me 😂

[@kevenhiemie]

A PPE power centrifuge oil filter that mount to the top of the engine, for easy serviceability, would really help keep that engine clean and living a long time.

[@freedomworx]

I had to look that one up. 👍

I appreciate it. There is a full build series on the Busted Knuckle Films channel. kzbin.info/www/bejne/g6KWZ3yihdWFodE

[@CaptK-py8rq]

Good video, thanks. I bought the FASS for my 2004 Chevy 6.6 Duramax, I liked the 5/8" long sweep tube in the pump opposed to the smaller 1/2" 90-degree tight bend on the Air Dog. Bought the filter delete from FASS but it would not stop leaking, had to take it off, put a new filter and housing on instead, now I have a nice aluminum filter delete paperweight I can't do squat with. Anyone else have that problem with the filter delete not working? I increased my highway mileage about 1.5 -2 mpg. I typically get around 27-28 mpg on the highway empty and hauling around 22 mpg, depends on the ambient temp. I'm all stock on my 2004 dually crew cab so I installed the 100 series, just turned over 112,120 miles when I got the safety inspection the other day. I highly recommend everyone do this for your diesels. It's $700 well spent. I always buy new trucks and take care of what I have. Still have a 1992 Ford F-350 dually crew with the 7.3 and 5 speed manual.

[@freedomworx]

27 MPG? You driving downhill the entire time?

[@robertkenney-oles5948]

My 04 LLY can also pull mid 20's if I am careful, also a crew cab dually with a mild tune@@freedomworx

[@Blue_Collar_Hunter]

I have a 2011 LML I installed this same pump on, w/ the WC Fab mount, using CAT filter, I also installed a sump pump on the bottom of the tank and did a fuel filter bypass delete under the hood removing the original fuel filter assembly. Everything works like a champ. I did that a couple years ago but saw this video and had to check it out.

[@freedomworx]

Yeah, the factory system is not the best design. It was almost good enough.

[@Peak_Precision]

Prime the pump and party 👊 Great videos 👍

[@garykortus6260]

This was the best video on installing a lift pump, thanks. Do you have one on replacing cooling lines from the transmission?

[@freedomworx]

Fortunately, I haven’t needed to replace them yet.

[@cliftonsr]

I guess you could buy that fitting that Fass uses to go to the suction line and put it into the plumping of the AirDog setup and you could do the same bypass the lift pump scenario if you had the lift pump fail to take it out of the system loop.

[@freedomworx]

You could. 👍

[@stevenm.hollis4429]

Great video. I own a 5.9 Cummins. But this was helpful. By the way I like your excursion nice rig. Again keep up the good work… Cheers

[@freedomworx]

I appreciate it. I’ve got some 5.9 content coming up. Working on it right now. 👍

[@white24valve]

New subscriber!! Have a 381,000 plus mile LLY.Recieved new Bosch injectors and a Fass 100 today. I have always bought the 150 or 165pump and truck would start loping a little. Soni would have to remove the ball ans spring and cut 1 to 1 and half coil off of the spring to lower the psi sent to the engine. Duramaxs like to see about 5 to 7 psi without the loping issue! Awesome video!!

[@freedomworx]

Thanks for the support. Yeah, some Duramax engines are more picky about lift pump pressure than others. My LBZ idles just fine though 👍

[@fatboyrob95]

I ran the filter bowl delete from FASS pitch wasn’t the same as the housing had to use a strap wrench to tighten to stop leak. Had work in cold weather and started to leak till it warmed up. Ended up just running the housing delete. Tried two different filter bowl deletes same issue.

[@freedomworx]

I bought an XDP Filter delete. We’ll see how it goes.

[@TonyReilly-mt7uu]

Great info, thanks. Interested to find out how the Baldwin filters work with the FASS system.

[@freedomworx]

I’m sure they fill work fine. Unless FASS decides to start sponsoring me, I’ll probably be switching when it’s time to change them out 😉

[@stans5270]

Good call on the hard spiral wrap. At 17:34 it shows the hose going right against 3 layers of body sheet metal. I would add more protection in areas like that against chaffing by installing a stainless steel hose clamp over the wrap so that the sheet metal rubs against the hose clamp and not the wrap. At 650GPM, that pump would empty your tank before you could shut off the engine. At over $5 per gallon, better safe than sorry.

[@freedomworx]

Gallon Per Hour 😉

[@stans5270]

[@travenstokes]

Those magnetic mounts are awesome. Glad I watched the whole video😂

I run Baldwin filters,and I did have water in my system, I only noticed it when it froze up in the below zero weather,I have since put a heater on,fast sells it.never had an issue,I always check the fuel water separate when it is warmed up and shut off.drain into a clear cup and let it set.peace of mind

[@freedomworx]

Yeah we don't have to worry about freezing fuel here in Georgia. If it's ever that cold here, we just shut down.

[@legionofanon]

On your back working above your face, like at 11:24 i would also add a face shield. I can't count how much dirt that has still ended up in my eyes even with safety glasses on, and a face shield just deflects it all. Even the super cheap like $6 one at harbor freight is totally worth it

[@freedomworx]

Yeah it would have been nice. That was rough.

[@t.l.robinson2162]

I run an Air Dog because I know a few people who have had problems with Fass filters . I've known a few trucks that has had their lift pumps stolen. I always mount lift pumps where they can't be seen unless you are under the truck.

[@freedomworx]

Folks steeling lift pumps? What’s the world coming to 😂😂

[@2015_Rubicnn]

I recommend the Fleece sending unit for the lift pump. I think the Airdog has a better laid out kit, and the mounting location is on the inside of frame.

[@freedomworx]

The Fleece system is good. A just wanted the filtration and pump all in one package.

[@2015_Rubicnn]

@@freedomworx I'm talking about the sending unit, not the lift pump version.

[@robertkenney-oles5948]

Rust belt guys DEFINITELY need to use a good amount of anti-seize on the mounting bolts if they ever hope to get it apart ever again.

[@freedomworx]

I couldn't live that rust belt life. I'm used to trucks lasting 40 years before they rust.

[@ronaldbabbitt6318]

Hey brother the Air Dog 4G 165gph has a bypass ✔️it can be off and still allows fuel to flow as normal without lift pump 👍🤠

[@freedomworx]

That’s good to know. Hopefully I’ll never have to find out 😎

[@ScottFanello]

FYI... I've had my pump blow a fuse a few times in -20 degree weather due to gelling... cp4 still managed to draw fuel from the tank through the FASS.

[@freedomworx]

Interesting. That’s good to know 👍

BD makes a fuel heater for airdogs, which I think fits fass too. Worth it if you live in a cold climate

[@chunkyharper9467]

I wonder if putting a shop vac into the fuel fill would create enough vacuum to keep that fuel cooler hose from leaking with a fill tank?

[@freedomworx]

Might be enough to implode the tank 😂😉

[@AyyItsJk]

Used this when installing mine last night. Went beautifully. Have you had any issues with 1/4 tank and it not priming? Heard it’s hit or miss

I haven’t had an issues since installing the lift pump. Had some before.

[@precisetransportltd.7254]

Yep I have an air dog and sure as shit dobern stranded a few times on my dodge 2500 now I'm installing one on my duramax so I guess we'll see on that aspect

[@SubePelayo928]

I have an air dog 165 on my truck currently. It’s been on there for about 9’years now and it’s finally slowing down. I bought a FASS100 and have yet to install it. What are the ports capped by the red plugs? Is not necessary to remove the caps and plug them?

[@freedomworx]

Those are heater ports. Coolant would flow through them if they were In use. It’s just an open cavity, so the plastic plugs are fine.

[@dandable]

Is that 25MM or 30MM round you’re using as a pointer? I used to manage the medium cal procurement team for the Air Force.

[@danieldilts7323]

Are you worried about the 1/4 tank and the pump runs dry? It happened to me - you can install a sump to eliminate that issue

[@freedomworx]

That’s certainly an option. But I plan to make more power, so I went ahead and got a lift pump.

[@victorsidingguy4371]

Hello how much pressure should I put to the pump for lb7 2003?

[@freedomworx]

I wouldn’t know. I’ve got an LBZ 😉. I take it on faith that FASS and AirDog set the pump pressure appropriate for the application.

[@FORGETYOU8]

Does it come with the hoses as a kit

[@freedomworx]

Yep. The only thing that didnt come with the kit was the hose wrap and magnetic zip tie holders I used.

[@Blackcloud_Garage]

What is that hose clamp at 8:21? Thanks.

[@freedomworx]

These: amzn.to/3TVUDCT

[@jaffasoft8976]

How do you know the psi it put up to the injection pump? If it needs ti be regulated can it regulate?

[@freedomworx]

There is a regulator incorporated into the FASS assembly. It’s designed to be 8-10PSI.

[@jaffasoft8976]

That be cool. Probably just enough to help push my waste veg oil as regular VE type pump struggling but I shouldn’t put it under too much pressure sucking either.

[@freedomworx]

It’s different depending on the application. A Duramax CP3 pump doesn’t like any more than that pressure. But the FASS system for a 12 Valve P-Pump motor is significantly higher than 10 PSI. Not sure about the VE systems though.

[@xtremeboost7]

The fuse unkownly blew on my air dog, and my cummins continued to run for months.

It’s in there, you just have to listen 🤷🏻‍♂️. Filters and plumbing are the only real difference.

Have you ever had one fail on you?

[@truckerron]

Wrong title... WASTE OF TIME!!!

[@freedomworx]

The only difference between the two is the plumbing, and the filter style, and I explained that in the video. Yeah the Airdog has adjustable pressure, but nobody adjusts the pressure so it’s a more point.

[@BiggusDickus2]

You either run Fass or you pee sitting down with airdog
