I just did this yesterday. It didnt work very good. I got the adapter/hose without the gauge on it. The engine was running and he ac was on max. Only about an 1/8th of the can or so was empty after about 10 minutes. The ac did not get any colder either.

Could I try it again as I did not take the adapter off of the can?
