After a long and hard road with this Air Dog 165 I've finally given up on it, everybody knows the story about it so I'm not even gonna go there. Basically what I'm looking for is what all ill need to completely redo my fuel system? I'm going to be using the fuelab 41402 and taking all the stock lines out and using bigger ones...I'm not running a reg return as of now but is it a must when you run this type of system? I'm not much of a fuel guy so I'm pretty lost when it comes to this, what all do I need to get everything working properly. Thanks guys
