Re: Need help find AC leak?
Make sure its not your gauge connections leaking. Disconnect the high side hose & put the cap on. then try just using the low side. You may have to sacrifice a can of Freon & charge it with one can. Then you can listen for the leak or put some liquid soap around suspected leak spots. Most of the time when I can't contain the vacuum it has been my equipment. Of coarse my equipment is 60 years old.
