Blazer Forum - Chevy Blazer Forums - A/C High Side Line Leaking

I just had some a/c work done today. My system wasn't holding pressure and we found the leak. The leak is coming from the high side service port itself. I went to the auto parts store and got a replacement for $3, but I got a closer look at the port and it is welded on to the line itself.

I can't replace the service port so I have to replace the line itself. Does anyone if there is any websites that sell this part or can anyone give me price on the part for a GM dealership?

Again, it is the high side service port going from the condenser to the evaporater, not the low side port located on the accumulator. Also, it is not the rubber hose coming from the compressor. Hope that clears up any confussion.
