I am looking for a low side 134A service port which can be spliced into the low side AC hose to provide a more convientient location for charging the AC system on my '88 240 rather than using the port on the compressor. It is my understanding that certain AC shops installed such a fitting when they converted certain cars to 134A. The fitting plugs into the 1/2 ID low pressure house. I resently met someone who has one of these "spliced" ports installed on his car prior to him buying it.

I have tried all the usual sources like ACKits, local AC shops, Volvo dealers, local independent Volvo shops, and radiator shops but to no avail. If you know asources for such an animal please let me know.

Thanks for your help.
