Engine/Transmission (1998.5 - 2002) FASS and AIR DOG systems

[cmills]

Sorry if this is a dumb question, I have a carter pusher pump on my truck but am getting tired of the reliability issues I have been having, I keep hearing people talk about FASS and AIR DOG, but I guess I don't know anything about them. I have several questions, If somebody could answer that would be great.



How do these systems work?



Do they totally eliminate the lift pump?



what advantages do they have over just using a pusher pump like I have

been?



What is all involved in the installation process?



What is the difference between the two systems?



Approximate cost?





Sorry for all the questions!



thanks,

Cory

I don't know, you would have to ask Charles, (The dad, AirDog) or Brad (His son, FASS).



Yup. Use the lift pump elimination ritual. After the FASS or AirDog is installed, take the old lift pump and beat it with a sledgehammer, cement truck or locomotive, whatever is lying around.



Advantage? That's easy. The FASS and AirDog actually PUMP diesel fuel. Go figure.



Another easy one. Get your mother in law (she ain't doin' nothin, anyway) to hang it off the frame rail and plumb it up. Tell her to use some bigger fuel line. I went to Kenworth here in Ft. Wayne and got some 7/16 ID Fuel line and went straight to the VP with a 90 degree fitting I got from Reb B. out in California. My FASS is used and it was in an accident. Now it's on MY truck and it's STILL running.



One (the AirDog) is a decendant of the giant Fuel Preporator used by hotrod OTR owner operators and invented by Charles Ekstam. The FASS is a copy of the AirDog and was introduced to the pick up market by Mr. Ekstams son, Brad. The differences between the two units? One is Blue and the FASS is red. That ol'e Brad managed to wrangle one of his dad's biggest customers over to the FASS camp, Pittsburgh Power, builder of some of the finest owner operator diesel engines money can buy. Something tells me dad was the engineering type and Brad graduated with a degree in marketing. I'll bet Thanksgiving at the ol'e Ekstam spread is fun.



5 to 6 hundy will get you in the ballpark.



P. S. Cory, say it with me. Search feature. :-laf

thanks, I did use the search feature and found a lot of posts about them, but they didn't really answer my questions.



thanks again,

which FASS pump

I have been looking at the FASS pumps and it seems that there is a 95GPH one and a 150GPH pump, could somebody tell me which one I need? I suppose the 95GPH one works up to a certain HP, is that right?



thanks,

I have also heard that the Fass and AirDog folks are father and son, but I heard it the other way around. (Fass was the father and the original, and AirDog was the son and came after FASS. The two were feuding or something..... I don't know or really care. ) What I do know is that they both work the same and AirDog is a little cheaper. They totally eliminate the stock LP and fuel filter canister if you would like. I chose to keep the oem fuel filter as an extra measure of protection, and cuz I had just replaced it! I might do away with it down the road.

Installation is easy except that I had to remove the bed. I might have been able to do it with the bed in place, but it was much easier removed and I was in need of gooseneck hitch replacement anyway.

I wish I could tell you more about pressures, etc. but my ECM is bad and truck has been in shop since installation, AND I have gone rounds with quadzilla concerning a fuel psi gauge. (See my other posts)

Anyway, point being this: GET ONE!!

You will not be sorry!!



p. s. Cory, the GPH is directly in relation to the horsepower you need. A call to AirDog will set you straight. They are great to deal with and will actually answer the phone.

Which one is easier to install? Which one is quieter? I have also heard good things about the GDP systems, but I don't know if they claim to remove air from the fuel, hopefully someone more informed than me will comment.

The Airdog 100 can be installed with fuel tank and

bed in place. The 150 you will need to remove one

or the other. I just bought the 150.

Anybody know how high of horsepower you can go with the AIR DOG 100GPH or the

FASS 95GPH

Airdog Fp-100

With the AIRDOG FP-100, since my truck is all stock other than 275 injectors and a boost elbow will I need to upgrade any fuel lines or fittings or will I be okay with what is there? And I assume continuing to use the regular fuel filter would be too restrictive right, so I suppose I can just leave it out and have the empty canister?



thanks,

The FASS 95 is good for over 500HP at the wheels.

NOPE it comes with new fuel lines(blue)---i did mine that way and no problems(empty cannister---keeps the fuel heater--may help a bit). The stock fuel cannister will be too restrictive---i tried for 15 minutes and then pulled the stock filter out. I noticed that my pressure from the fuel gauge would take 5-10 second to drop with the factory filter too,and the Airdog seemed to be working a little harder pushing through two filters. So far i just left well enough alone and all is OK. DW
