I’ve touched every part of my 73 Canyonlands I know first hand and have made all of my (many) repairs. With regards to the air compressor. I have learned that the original is slow…..very slow to get to 100-120 psi (mine is set at 120 psi). And I’m not sure that a perfect original was ever fast. Bob, the on/off switch is the ignition switch. It runs in the on and acc position. There should be an out-board pressure switch mounted next to the Dana Compressor. This will shut off the compressor at a predetermined adjustable psi. The storage tank is located on the passenger side of the vehicle very near underneath the two batteries. The tank has a drain, a safety relief valve and mine included a scrader valve. I’ve added a run LED in the warning panel but the compressor is so noisy that I hardly need a light. I’ve also added a guage at the tank and a QD for the unexpected. I have been using mine for the past 1 year during the restoration and surprisingly it has performed better than expected.

I commend you on your efforts.

I know absolutely NOTHING about the 1973 air ride system. So I know I'm LOST. Then with parts missing. There is a pressure shut off switch. Were is the manual off switch. The right side controls are not there. This part of this GMC is a mess. Bob Dunahugh
