Me and my buddy were tossing up the idea of running a AirDog 2 in my 96 powerstroke and being able to regulate through the airdog. Now we were think about feeding back of the heads and coming out of the front of the heads and returning to tank, I wanna get rid of the valley mounted regulated return I have now, do I need to have a regulated return and if so can I mount it on frame out of the way?
