Before I give up or start over I'd like to verify that the hissing sound in the video below is that of a leak and not some normal process. It is coming from near the orifice tube which I replaced. I was surprised to hear it since I drew down vacuum and the vacuum held for an hour. I then recharged the system and the ac is blowing cold. The sound ends about 30 seconds after shutting off the engine.
Orifice tube was in backwards. Put it in the correct way and the hissing stopped.
