is there any difference between the two?

 

AirDog is more compact than the Fass so it doesn't hang down off the frame as far. AD is quieter than the Fass. AD has better prices. Also AD has a better design IMO. But they are pretty much the same beast being that Dad owns AD and son owns Fass....

 

have either had any issues with the pumps?

 

Can't help ya there, I've had no experience with either but I am getting and AD 150.

 

no problems with the pumps really till you get to the high pressure fass but they both offer lifetime warranties so go with the one you want. I run the fass no issues. they sponsor around here where I am at so I support them

 

i have an airdog 150 and love it. pretty much same thing anymore its all in which name you want and how much you wanna spend.

 

thats cool, i have seen the AD for a tick cheaper than the FASS, just wasnt sure what the difference was.

also has anyone seen a mileage and or power increase from using these air seperating pumps?

thanks guys!

 

Btw its nice to see ya made it over here, I talked to ya on DooTalk about the site... My SN is Jake77 over there.

 

I'm running the AD 100 and Travis is running the AD150 with zero issues.
I know the AD is on sale right now for $499 with lifetime warranty.

 

Red, im glad you talked to me about this site.. way better than some of the other diesel sites ive been on.. thanks!!
