With the controls properly modified and refit to the dash, we're in the home stretch now with our hose kit installation. There are only three loose hoses to install under the hood and they use different fitting sizes so it's impossible to mix them up. Route the long lines first, being sure to lubricate and install the required O-rings on the end fittings. Don't tighten one end without starting the opposite end fitting first. This will allow you to gently rotate the hose for best routing and clearance before tightening up the end fittings. As before, be sure to use two wrenches to prevent damaging the tube fittings.
