Just a heads-up, did you know they used to make 2 of em. One was just a tank you could use as a reservoir(I use one for my liq i/c) and the other had the plumbing installed and set-up to run as a gas tank. What did you intend to use it for? The plumbed gas tank is a lot rarer than the reservoir tank. If it's the reservoir tank you'll just have to install plumbing to use it for whatever you'd like. I had to drill and add my own plumbing to use it for my liquid i/c reservoir.
