When deciding what to use for an air tank, and how big that tank should be, I remembered the AT2K tank and thought "heck... this is at least as big as that, and I'd be fine with half an AT2K's range"
So, before I assemble everything, my question: In your opinion, would an air tank of this size be sufficient to fire two darts in two barrels 50-70 feet? If not, how big should it be? (Those are 3/4" PVC elbows)

I jury-rigged it together with hot glue and electrical tape, and after just one or two pumps it got very hard to pump... by the time I could get my hands off the pump and to the trigger, however, most of the air had leaked out, so I was not able to ascertain on my own if this tank was sufficient.
Additionally, I'm currently just hooking the tank up to the air pump... I searched the homemade forum a bit and saw "check valves" mentioned -- would it make sense to have one, given that I intend to use a storebought pump?
