i just currently started installing the air dog 2 on my 2007. 5 1 ton and got everything finished up. when i went to bleed the air out. there is no fuel being pushed up to the injector pump. we went through everything from the tank to the motor and there is nothing missing. i noticed though that the fuel in and the engine ports are tight as hell but still have about 4 or 5 threads showing. i am afraid to try and tighten them down anymore to avoid cracking anything. just figured i would ask the pros on this type of thing since most of yall are running it and obviously yours are working right lol. thank you.
