I'm looking at the Airdog system. The Fass dealer here says the Airdogs are plastic. What parts on the Airdog are plastic compared to my Fass? And does this affect any performance or longevity issues down the road? 
What's the difference in the AirDog system?

this year at TS Outlaw in Bowling Green they had the airdog booth there. and from what i can tell and what he told us and compared with FASS, airdog is built extremely better. i dont run either one as of yet but if i had to choose i would go airdog now. and as far as being plastic i didnt see anything cheap about them.

There is nothing plastic on the AirDog. The AirDog is a superior product and always has been.
A good example of this is a CR truck running a modded CP3. A 100GPH glacier or AirDog will feed a Modded CP3, but it takes a special FASS 150 set at 40 psi to keep up with it. Even running the FASS 150 set at 40psi, it would drop to 20psi under full fuel. The AirDog100 set on 18-20 psi would support it just fine with no pressure drop. When the modded CP3s came out guys were told to upgrade to a 150 or even larger FASS. They assumed the AirDogs and Glaciers would not handle it, so they were telling AirDog/Glacier owners they would have to switch to a FASS. The truth is the only guys that had to step up to a FASS 150 were guys running a FASS 95. The AirDog has been a very good system and has proven to outperform comparable products (FASS 95) as well as what should be a higher performing system (FASS 150).

correct, any company that puts down Airdog believe me, only sells FASS. we have delt w/ both companies and in the end choose to carry Airdog for a reason. they make a great kit and if you look at my thread about the comparison between the two it speaks for itself.

I've seen a modded cp3 suck an airdog100 down to 10psi and a walbro down to 0psi.
What makes an airdog superior in it's construction? All I hear is that it's built better but I have yet to see any proof that it's built better.
Not trying to start a fight, I'm just curious and want some details.

I've currently got a AirDog 150 in my truck. I'm not exactly going to take mine apart to look it over but... So far the pressure is very constant and stays above 15 PSI always. Normally idles at about 17-17.5 PSI.:w:

I think you have an install issue. They do not drop when installed properly.
There are alot of things making them superior, but to list a few:
More compact package
1/2 inch lines
superior filtration
superior air removal
better finish
quieter
There used to be several other things, but FASS has copied that stuff - such as the FASS return flow issue and wiring

:agree2:
As with a FASS system even there web site will NOT give out contact information. :thud:The company will not deal directly with a customer or warranty issue... The site request you contact your local dealer... :w: Now with a AirDog you can contact PureFlow Technologies...

As for FASS contact information...

Doesn't say much for Diesel Performance Products, Inc. (DPP) :w:
The reason a AirDog 100 was sucked down is it uses the stock pickup tube in the tank... Where a AirDog 150 uses a draw straw (1/2") pickup tube and the stock tube in no longer used... When I first hook up my AirDog I didn't have the time for the installation of the draw straw. So I ran it hooked up to my stock pickup assembly... I could suck it down to 10-12 PSI easy with my Edge Comp on 5x5... But now with the draw straw no longer happening...

I have talked to Charlie directly on a few occasions, and he is ALWAYS more than willing to help me with any problems...But I have yet to have any malfunctions with my Dog. The problems I had involved my own noggin:thud::thud::lol3:

Don't get me wrong I wasn't aiming to start a war either... But normally when I got warranty issues I normally contact the manufacture... Not a dealer... Like when my Edge Comp died I contacted Edge Products to deal with the problem not Diesel Nut Motorsports (which was the site sponsor that sold it to me.)
This is one of the factors that sold me on AirDog because I could contact a manufacture and get information, warranty issues or parts as needed...

When was the last time Chrysler took your call, without you seeing the local dealer first? Fass wants LOCAL support, it's their idea of getting results faster...
I don't mean to start a war (seems to be the thread tag line) but everytime the AD cheerleading begins this is brought up to be a negative. I am a dealer and I regularly get calls on both systems. Normally sales calls on the product I sell and trouble shooting on the other brand. I am not saying AD fails more, I am saying the customers buying these things are doing it on a price proposition and when they need help they can't get it locally.
If the system and service is so great, why do people that own them keep bothering me

This truck has had a draw straw in the tank since the walbro and he was still drawing it down.
What makes it have superior filtering? You can get a FASS with 2micron filters.
What makes it have superior air removal?
What makes it a better finish? I personally like the red.
I still have yet to see proof that 1/2" lines make any difference on a VP truck. I've run both 1/2" and 3/8" and saw no difference in pressure, pressure drop, performance, etc. So I don't buy the 1/2" line makes it better. I've worked on vp trucks over 600hp with both lines and never saw any difference. And 95gph FASS will support over 600hp and only drop 2psi at WOT. I haven't played around enough with the 3rd gens to voice an opinion on that.
Yall still haven't answered my questions as to what makes it superior. You keep throwing out the same answer which it just is. It all sounds like a sales pitch. I'm asking for real data between the two. Have you ever run any flow tests or filtering tests or what not?

IMHO...... both the fass and airdog are comparable systems, as far as both do the job. here's how the airdog does it BETTER
1) first and foremost, its cheaper, over $100 cheaper
2) the airdog is a more complete kit, comes with everything from pickup tube to vp connection, wiring, relay, and wiring for a warning light
3) the airdog is smaller, fits tucked up into the frame
4) although the airdog is loud compared to the stock pump its much quieter than the fass
5) airdog is blue :lol3:

If your drawing it down with a draw straw, you have other issues.
Last time I checked a 2 micron Stratapore for a FASS was $82, but maybe they have something new.
Superior air removel, that one is obvious if you actually have worked on these systems as mush as you claim. If you do not understand, it removes air prefilter as well as on the clean side. If your going to do something, may as well do it right.
I understand what you are saying about what you have seen in requard to fuel line sizes. While it does work, it is not ideal. Do some studying on fluid dynamics.
The finish I am referring to is the way the FASS looks like it was run across a disk sander.
And yes, I have tested flow with not one but three flowmeters on the same engine at the same time(about $800 dollars worth) . I have a very good idea of exactly what is needed. Not only on a VP, but many different engines. I have experimented with many different brands of pumps.
I have not done any filter tests - I run Fleetguard and they will supply the SAE tests if you request them.

my stock lift pump i could only hear with the door open and the hood up, the air dog i can hear prime when i get in. the few people i know with the fass system are LOUD, you can hear the pump while driving, let alone idling, over straight pipes. either way, i see no reason to pay over $100 more for a fass.
