This is my on board air setup for my 94 Geo Tracker that I just installed. I wanted to have a way to pump up a tire or use air tools out on the trail when I am camping. I used a stock ac pump/ brackets/ belts off a Geo Tracker out of the junk yard. One no good home air compressor for the tank and fittings, Adjustable pressure switch, inline oiler, water/ oil separator, one way check valve, air release valve, air hose and some more stuff. Sorry for the shakiness . If you have any qustions fill free too ask. Thank you for looking at my project's.
