And I can not for the life of me fit the hose onto the low pressure port to charge my ac. I pressed the cap down and tried to fit it on the low pressure, I’m doing everything right, and I cant figure out why it wont fit. If I press it down while holding down the lever on the hose I will hear pressure escaping from the port but it wont attach.
