I spent most of last summer fixing A/C lines and the system worked great but
lost refrigerant after a few weeks.
Now I have an AC compresser that leaks dye from both end flanges and need to
replace it.
I'd suggest that you can get A/C pipes from FCP groton.
You need new O-rings
and also I'd go to Volvo and get new Clamps for the AC pipes that have the rubber inserts, since the rubber wore away and the clamps cut through the A/C pipes.

The pipes are expensive, so call FCP and see what the pipes and misc parts are,
Then add in maybe an hour or two labor for assembly evacuation and recharge, plus new refrigerant, and the price is up there. Then you eat dirt if something like the evaporator leaks the next day.

You need a lucky star!
