External Air Connection - 99 Adventurer or Similar

[mickey53usa]

OK, want to add external Air valve and connection to the on-board Air system. Think I found the proper "manifold" to use, has a schrader valve on top and a black plastic line on the bottom that goes somewhere. Six hex (allen) "ports" on the brass block. Plan to use an elbow to get the connection vertical, then a short straight section of pipe, then another elbow to bring it 90 degrees forward. A ball valve and then the female hose connector. Trying to figure out a way to support the fitting. It comes up along a piece of 1-1 1/4" box tubing the has the vacuum solenoid for the heating/AC system on it. Suggestions? How have you done this? Pictures?
Thanks
