Does anyone run a Air Dog or FASS? If so, did you notice any differences in fuel economy or engine performance?

Trying to decide if it's worth it for my 2011. The only mod's I'll be doing is the oil bypass, tuner and DPF delete. No racing. Just an everyday driver with the occasional towing.

Going to give this thread a bump cause I was just looking at the Air Dog 150 the other day and was wondering the same questions you were asking.

So how bout it anyone on the boards running one or know anyone who is running one???

Pro's and Con's are more then welcome!!

Anyone?

Bump

I put a FASS pump on my Pete after new fuel lines and filter housing trying to get air out. Nothing seemed to help, but the FASS pump cleared it all up. Can't say much for milage on the truck but I'd like to have one on the pick up.

its a good investment if u have the $$ . The stock fuel system lacks a lot to be desired. Clean fuel and good constant pressure is essential for the life of this common rail injection system.
