When I originally bought my 1992 745 almost 4 years ago, the air wasn't working, but had been converted to R134a by the Volvo dealer. Not knowing what was the problem and not wanting to start spending a lot of money, I first tried charging it with one of those HC refrigerant kits, but there was a bad leak. I found it was the condenser to compressor line and replaced it, but never got around to charging the system.

Today I decided to get it professionally tested and charged because I didn't to mess with the HC stuff since once you do that, commercial shops won't want to touch it for fear of contamination, or really fleece you if they do. Well, it turned out that after $100 I still had a leak, this time in the "high pressure line". The mechanic pointed out the skinnier of the two lines that run on top of the frame rail on the passenger side of the engine compartment. It looks like it runs from the firewall to under the rad. The service advisor then told me that not one of these available in North America, presumably according to Volvo.

I just checked FCP Groton just now and see that they don't even list it. Can anyone here familiar with these systems identify this line for me and steer me to a Volvo parts supplier that would have it?

Thanks.
