Here's where I 'deviated' from the normal method of running the hoses behind the rocker panels. I routed the A/C and heater hoses inside the longitudinals through the stock heater pipes. I cut access openings on the top of the longs next to the wheelwells in order to remove the old 'J' stovepipes. The metal pipes have too sharp of a bend to route and insert hoses through them. There is also a plastic fitting on the pipe which narrows-down the opening, so that was removed too. The new hoses run inside the fiberglass insulated pipes except for a foot or so toward the front. I wrap the exposed sections of the heater hoses and the A/C suction hose (returning from the evaporator) with Armaflex insulation wrap. This will reduce unwanted heat radiation into the car, and prevent any condensation. Condensation is not normally much of a problem on rubber barrier hoses anyway, expecially in Tucson.
Above is the #10 suction-side hose from the evaporator routing across under the dash and into the long to go back to the compressor. Also is the #8 discharge-side hose from the compressor going up to the condenser. I found a boxed-channel under the gas tank that allowed the hose to make a direct shot into the front trunk area.
Once I'm done I'll cover the access openings with new steel covers. I'm debating whether to screw them in or spot weld them in a few places.
