I have two friends one has a fass and one has airdog. They both seem pretty good no problems. I have the raptor and I havent had any problems with it. It was on there when i got it or I would have put a fass on it! Another plus to the lift pump comes into play when changing the fuel filter found that out friday when i changed mine. loosen the bleed screw and turn the key on til fluid comes out. Makes for alot less pumping of the primer.:thumb:
