(12) The main 3/8-inch manifold tubing is run along an existing wiring loom and secured with supplied nylon ties. The stiff polyethylene tubing is used to cover the manifold tubing to prevent chafing wherever a tie is used. Alternately, the manifold tubing can be secured by drilling 3/16-inch holes along the plumbing route and the mountable cable ties used. The polyurethane tubing has a temperature limit of 160 degrees, so make sure to route it away from heat sources. The 3/8-inch manifold tubing is then cut near the front wheel, and the 3/8-inch to 1/4-inch T installed (arrow). The 1/4-inch tubing is routed to the front Schrader valve mounted earlier. (13) Here you can see the route from the main 3/8-inch manifold tubing to the T-fitting and the 1/4-inch tubing running to the front Schrader valve. The process is then repeated on the other side of the vehicle. (14) All of the manifold tubing converges at the control panel under the hood. The 3/8-inch manifold tubing from either side of the vehicle is tied to the main control valve with a 3/8-inch T-fitting. All of the peripherals — i.e. the gauge, the Schrader valve, the pressure relief valve and the onboard air line — T into the main manifold. It’s easier to install than it is to explain, believe us. The air compressor was then plumbed into the system with a male D-type quick-disconnect fitting and 1/4-inch FIP by 1/4-inch OD push-to-connect adapter. The user now has three options for airing-up (female D-type from an air hose, the Schrader valve or the onboard air compressor that is plumbed in).
(9) Dually kits use a male D-type connector at the rear. First, a Unibit is used to drill a .790-inch hole in the rocker panel near the tires, then a D-type push-to-connect bulkhead adapter is installed using a nut on the other side. (10) The male D-type fitting is then installed into the bulkhead adapter and tightened. Typically, a female fitting is used on the supply side of an air system, but here a female D-type connector is more likely to become clogged with dirt and debris. A male fitting has no moving parts, and the plastic cap keeps dirt out. (11) Here is the rear D-type fitting (with cap) and adapter, with the 3/8-inch polyurethane manifold tubing pushed into place.
