Help! I have spent a lot of time searching previous posts and have received some conflicting information regarding the A/C low pressure valve.

I have a 1986 944 na.

The posts seem to indicate that the larger of the two lines by the strut tower is the low pressure side. They also indicate that if there is only one valve there it is the high pressure valve.

I have only one valve - on the larger of the two lines (on the left when looking at the two next to each other). My question is; where is the low pressure valve on my car?

Thanks in advance for the help.

The bigger of the two lines is the low pressure. On some cars the high pressure tap is located on the compressor connection (underneath the car)

That certainly makes things easier. Thank you VERY much for the clarification.

Yep - bigger one by the driver's side strut tower. It's closer to the engine too, to help you nail it down. I believe you can also fill at the port on the compressor itself.
