I'm not talking about the lines at the compressor. I'm talking about the thickness of the lines right where the ports are attached, they should be different sizes.
It has been my experience with GM cars that the upper one will be the high side if it's by the radiator.
Also the low port itself will probably be larger.
Sometimes the low side will be on the accumulator.
Tell me what V6 you have and I'll try to get more info.
