That’s funny you mention the valve on that hose. I noticed it when I was originally hooking it all up and that was the one thing I wasn’t sure of. My ONLY thought for when I try again today was to do exactly that, switch it around and see what happens! Thanks for that confirmation, hopefully...
Really hoping for some help with recharging my AC system. I’ve recently got all my hoses replaced since a mechanic confirmed I had a leak. Now with all high pressure hoses, connected tightly with thread locker, I moved on to vacuuming the system and recharging it. I had to get the retrofit kit...
