Updated the OBA sytem. Manifold in the engine has a universal coupler, just in case someone else needs a fill. The line going below the tee redirects to a 4-port manifold that splits to 4 tubes holding the recoil hoses. The line that come through the tee goes through the firewall to another manifold inside the cabin. From the interior manifold, I have a ball valve to control deflating, and the compressor switch to control inflating. The interior manifold also has a pressure gauge, so I can control the pressure of my tires from the cabin. The thought process behind this is two-fold: First, so I never have to worry about packing a hose for inflating/deflating again (saves space in the cargo area), and; secondly, I do a lot of snow wheeling and will be nice to deflate and inflate from the comforts of the cabin - it will help in inclement weather, as well. Lastly, this is just a proof of concept. Right now, the tubes are PVC and held on via metal clamps. The final version will be thick stainless steel tubing welded to the sliders. Or, if I can find a smaller diameter recoil hose, I will weld it above the slider connecting bridges.
