Thanks for the reply. I've been searching and I can't find the pipe joint disconnector tool or a youtube video with the hose clamp trick. Could you please provide a link?
nm, it's called a spring lock coupling disconnect tool.

Glad I found this thread. I suspect my evaporator is leaking so I'm replacing it tomorrow. How do I disconnect the lp line in the engine bay? The hp line has a nut but I'm not familiar with the connector on the lp line. Any help is appreciated. Thanks!
