Where is the low pressure port?

DannyXJ said:

I got a used 91 a/c compressor from a salvage yard, and I think they may have switched the valves when the screwed them back on. It is a Sanden 709T. There are two ports--one labled "S" and one labled "D". Can someone tell me which port is low and which is high? TIA
