What does the ac hose have to do with the red line? Do you mean the rpm gauge?

It would really help to know the high and low pressure readings?Also if there is plenty of air being pulled thru the radiator?Iam not there to see the readings so iam flying blind without the info. The number one thing I have seen cause a pressure issue on those cars are the expansion valves.
