Reese Airborne

In answering craig7h I ran an airline with quick disconnects from the truck to the pin box. The piping on the Airborne from the factory is made to inflate with an air chuck. I took out that cheap plastic airline and piped it with brass fittings from the bottom of the airbag, installed a tee with a "0 to 100" lb pressure gauge with an other tee with a valve to bleed off air if over filled. On the truck end I installed in a convenient location a spring loaded rocker switch "on off on" next to the switch I installed a digital pressure gauge. Make sure it is easily visible and within easy reach. The compressor on the Freightliner is built in so I tapped into one of the air tanks ran a line to the back and installed two solenoid valves. The first valve is on the main line from the tank. Then I installed a three inch space nipple between the tee fitting and first valve. The second valve is piped into the side of the tee as a bleed off valve. Next comes another space nipple with a tee. On this tee install the digital pressure sensor for the gauge in the truck. Then from the sensor a short piece of pipe to an air hose that is long enough to reach the other quick disconnect. Make sure the air hose from truck to pin box is long enough for the turning radius of the pin box. On the Ford I had to install air compressor and tank to accomplish this. All solenoid valves, rocker switch, digital gauge and pressure sensor were purchased on E-Bay, the plumbing at local hardware store. When running the wires pull a couple of spares for in case of who knows what. I ran #14 gauge wire. Good luck "Weekend project"
