okay im gettin ready to buy a fuel system i and was going to order an airdog 2 and i heard purflow airdog has a different owner and has went down ill considerably and the fass titanium series aint lookin to bad but i just want some updated opinions for 2014 on who has the superior unit so lets hear it people.

 

Fass has always been superior. Air dog always had an extremely high failure rate but managed to cover it up for a while. They sold out when they could no longer keep up the cover ups.

i like fass. I only installed one airdog and it was because the guy insisted thats what he wanted. After a month of work, a new injector pump, beating my head on the wall, and finally puting a fass on it, we found out that the clamp airdog sent wasn't strong enough and when the fuel level got below the clamp it would suck air. Airdog customer service was terrible. After installing everything per there directions the truck wouldn't start. I stayed on the phone with vinny at alligator for 2 hrs. and still didn't get it fixed. Next we decided that the pump must be bad. After taking it back off, air dog said they didn't have one on hand that they would have to build one the next day and ship it to me. 3 days later they finally got one built and shipped it, to arrive overnight after i had to pay i think 85 dollars shipping! The owner wanted the truck ready to drive to denver in mid july and i started all of this about the end of june. It shouldn't have been a big deal but it turned into one and cost me a lot of time and money. Alligator performance was very helpful through the whole thing and they wound up sending me a fass system which is still on the truck. In short i'm not an airdog fan!

 

are they any better or worse since they sold?

There are Thousands of complaints on Diesel forums about Airdog Failures

Conclusion is Airdog is cheap junk worse than a stock pump

Almost 5 years on my FASS HD150, through the frigid Canadian winters, absolutely no problems.
