Hey, guys, stupid question time. After replacing a couple coolant hoses a few weeks ago on my '67 VIP, I discovered this hose that's not connected to anything. I'm guessing maybe it's something to do with the A/C? The car currently doesn't have A/C equipped but originally had it. Also, this tube had a hose just kind of dangling off it -- no hose clamps or anything. So I'm not sure if it's related or if it's even supposed to connect to something? Thanks, guys!
