Low pressure A/C port

[ak_siberian]

Is the low pressure A/C port marked? Need to check why I'm not getting much cooling. TIA

it's the larger diameter hose when compared the high pressure. some caps have a L or H for each port.

Thank you kindly. I always spray some yellow paint on the cap to clearly mark it, not that the fittings would fit if you tried to wrong port.
