When you order a complete set from IBT, it will come with a tank tool (brilliant), plus the tank comes in a small plastic container, in a size similar to a film canister (I'm dating myself, I know). Anyhoo, the canister the tank comes in is called a "thingy" - and it can be used in a very simple way to prime a new carto....
You aren't dating yourself to me. I have a Slap Yo' Momma from Big Daddy Vapor, who invented them. The others all came later. I haven't tried the ones like IBTanked sells, but they are longer and I think the shorter ones are easier. I have also fiddled with my thingy. I don't have the patience to fiddle with the thingy long enough for it to work and my wrist gets tired. I can do it faster upside down with a condom.
I like how that came out...
