    I can't decide which one I want

    so my next modification is a lift pump either FASS fuel system or air dog 2 I can't decide which one because both seem to have very good reputation for quality products does anyone have any input on which one would be better or is it just a coin flip I'm not looking for an outrageous gallon per hour because I'm not going to push my truck passed 650 horsepower.

    I had issues with my Air Dog and they wouldn't stand behind it. My filters rusted internally and they were only a month old.

    Go Fass

    Air Dog has had a lot of very well documented problems with their lift pumps in the last 2-3 years. That being said I have an AD II 100gph pump that I bought new 4 years ago and have not had a single issue out of. It is currently feeding dual CP3's with 100% over Exergy's on my 800hp street truck. I'll also add that the handful of people that I know who are running Air Dog's new 4G lift pump have had nothing but good things to say about them. My advice would be to go with whoever offers the best warranty, and get either a FASS 90 or AD 100, either one will support your goal of 650hp. I'd also look into adding a sump as well. Anytime you can gravity feed your lift pump as opposed to it using a draw straw will add to it's life span. Good luck!

    Like others have said Air dog has seemed to have issues. They sold the company to another and it went south. FASS I've yet to read anything bad or very much. Now with that said I've had zero issues outta my air dog 2 165

    I got my first pump right after the acquisition. Then it started to blow fuses. I paid for an upgrade to the 165, which I had to replace also. It was fine for a while. Then I changed the fuel filters with official Air Dog filters. Figured it was the right thing to do! A month later, I lost 3 injectors. A few of you may remember that. Cost me a fortune. Several weeks later, I lost a couple more. I replaced them all. A couple were the new ones. Then I lost 2 more. What the hell? I previously eliminated everything but the filters. I actually had 2 filter sets. They rusted so bad, the overwhelmed the 2nd filter. When I contacted Air Dog, they were pompous about it. They would give me new filters. Forget about the $8000 I had invested in replacement injectors. . . . It was their fault.

    Turns out Air Dog had 4 different filter vendors and had the rusting problem already. That's what product liability insurance is for.
