The AC hoses right from the factory were noon barrier hoses. R-12 was 99 cents per pound, and Porsche decided to save the exense of barrier hoses, and use cheaper non barrier hoses. I tried for a couple of years to get cold air from teh factory stock system and it is just useless in 90+ temps in the sun. The factory AC is OK at night, or up to 85 degrees.
Replace the hoses, all the rubber AC hoses. They simply leak. Griffith's system is not cheap, but it is the best quality stuff out there. As you follow the instructions, you will say, dang that is a clever way to do that. And wow, this is a nice component.
