Check out my On-Board-Air setup

I finished my OBA tonight with the exception of the fitting for the Powertank. I need to make a bracket and like an idiot, I left valve open on the argon tank. I'll run to a buddy's house Sat and use his welder. Anyway here's how it works....

The first thing I did was modify the ARB wiring harness to hook up to factory LR switches for the compressor and the solonoid. The ARB pump runs to the manifold which has a glycerine filled gauge, a 100 psi safety pop off valve and a check valve. The manifold has two lines that run to each of the sliders which are used as air tanks. Because there is a possibility that I'll snap off a fitting, each slider can be isolated simply with the turn of a valve up by the frame. The plan is to fill the system wtih the Powertank before I go out wheeling and use the ARB compressor too keep the system pressurized. The check valve is necessary to keep the pressure in the system when it is not connected to the powertank. To connect the Powertank to the system I made a bracket with a male fitting that mounts near the tank. When I need it I just plug the tank in, fill the system, and shut the tank off. After solving all the little leaks the system holds pressure perfectly. I filled it to 100 psi last night and the needle didn't budge 24 hours later.

You're kidding, right?

There's no reason. I didn't feel like leaving a nice pump in the elements. As far as hearing the pump, trust me i can hear other people's from inside my truck. That compact isn't as loud as the regular pump either. Also, with my setup i can get 60+ hits of the locker before the pressure drops below 80 psi and starts the compressor. So I'm sure i'll get a full day of wheeling without hearing it at all.

Thanks. Yeah, I'm a little OCD. Almost as much as someone else on this board.

Craig to be honest, I'm not really that concerned. I'm sure the way I change parts the sliders will be gone before they rust. I'm thinking of putting an air dryer on the lines to the sliders, but haven't found one that I would like to use. Good ones are damn expensive. I'll keep looking.

Bri, just front. I love the Detroit too much. I did wire up both switches though just incase. . It'll be super easy. Just throw another solonoid on the manifold.

You're right I am a little bored right now. Just wait though. I have something else up my sleeve.
