that looks awesome. Put a light knurl on the cap to make it easier to grip..I had to try the threaded cap idea:

Because it is thin wall tubing, I selected a 28 TPI pitch. I probably would have been fine with 20 TPI. But it works, nice and smooth. I need to solder the flange onto it.
I think you could easily do that but for high volume flow like a gas can you need a return path for air to get back to the can. Alternatively you can buy those plastic vents and install one on the can.If it isn't leaking acetone, then you should be good!
Been thinking about a very similar project for a bunch of gas and diesel cans I have around here. The plastic cans are in great shape, the nozzle, not so much. Replacements are all aftermarket, and junk. Something like this (with a hose) would be a great way to fix that problem!
