Re: A slew of A/C questions
5150,
I might be able to help. I have a factory front and rear air 72 suburban. I replaced everything except the rear AC with an Old Air kit a year ago. Mine has a large Sanden compressor but yours would probably work. My suction line is Yee's between the compressor and firewall. The feed line is tee'd between the dryer and the compressor. The tees were a custom crimp job at a local AC shop. From the tees, the 2 lines run back down the backside of the passenger wheel well and follow the frame a bit. Then they run diagonally across to a point in front of the drivers rear wheel well and up into the body between the outer sheet metal and the interior panels. From there they run horizontally inside the body back to the D pillar where they travel up to the rear AC unit. I recently put in a full insulation kit and can't wait to find out how well the system works this year. It struggled a bit last year, but there was no insulation.
