Hey Gang,
Need some help installing an Air Force One reservoir in my coach #763. I can tee in for the air supply, but having a little trouble with the metered air. My coach has a 3/8" DOT air line out the back for a trailer, but this goes from 0psi up to about 50psi with full brake pedal. My understanding is I need to tee in to the brake system for the metered air, as it goes down when applying pedal. I really don't want to crawl under coach. Has anybody done this, and can they give me some poi
