Ok lol one more time! LOCKED up motors on a airdog will not bypass fuel i have had more trucks then i can count on my hands lock up airdogs and couldn't pull fuel to run. My fass locked up tight and i still was driving and wot fine just felt sluggish like i had a plugged filter i have had one pump failure in 6 years with fass stuff and that was my own pump. I dont sell ad anymore because i cant as a fass vip but if you cut a fass in half and a airdog you'll see were the fass is better far as flow
