Airdog II vs Fass

[powerstrokepribble]

I just learned that my lift pump may be going out on my truck and I was just curious which would be better the Airdog or the Fass. I have needing to get one on my truck anyways but now it is a must. So I was was curious which one is better or if there are even any differences? Also which model is best suited for 2004 6.0L PSD with simple mods (programmer, intake, exhaust, egr delete) with plans of maybe a bigger turbo and 90-150 hp injectors? Any help is appreciated. Thanks

I've had to send back my Airdog II pump twice in a year, but that may had been just a fluk. Their customer service has always been great with no hassles.

Hope this helps!

From everything that I have read between the two (which felt like a lot to me) both have faulty pumps with Airdog maybe having slightly fewer than FASS and FASS's customer service USE to be less than stellar and have left a sour taste in quite a few folks mouth such that they will never buy FASS again. The truth of the matter is that both companies warranty their pump for life (provided you send the warranty card in within 30 days of pump purchase. Otherwise forget coverage) and there are folks out there successfully running both systems. IMO the key to pump survival is the addition of a sump and maybe even a RR kit as this will do two things. One with the sump the pump is never starved for fuel until the tank is empty vice the 1/4 tank issues (some folks seem to have them while others dont). And two with the RR kit the pump has somewhere for the excess fuel to flow to. It keeps the pump from providing all of that flow and no where for it to go to so the pump is working against a wall and heats the motor up until it fails. Just my $.02 Take it for what it is worth.

Airdog. I wouldn't P*I*S*S on Fass because of all the money they cost me and left Granny stranded in North Carolina for a week. Didn't take but 3 months to get my LAST Fass fixed.

See what I was saying about some of the strong opinions on why folks dont like a particular brand??

I have had both of my trucks. I recommend AD2s to all my customers wanting fuel pumps. My FASS was noisy and left me stranded on the side of the road.
