So i was taking a load of end posts and highway stakes to my job site, when all of a sudden i had to hit my brakes to stop in time before running over a small car.
Well my load dicided to keep on going and smashed my tool box. my air system was tucked inside there and luckly nothing broke.
Well i finnaly was able to get a new box and finished putting the hardware back into my box.
Reworked it a little and found a pressure regulator to drop the psi down to 150 from 200. Also i dicided to chuck the 3/8" line and go full 1/2" line to the horn. The metal tube that goes from the tank is also 1/2" tubing.
Cant wait till i rewire everything tommorow and get it pumping 
here is a picture!
