2. 3/4 inch pvc hose. It is rated for up to 120 I'm pretty sure.
Right now the magazine isn't done so we don't really know the firing rate, but it should be fairly fast as after it shoots it just unlocks the shell, ejects the shell, then lets the next shell fall down and finally seals the shell and it is ready to shoot.

As an Ex-3647 student... i remember that tank...
The smaller grey tank was obtained from McMaster-Carr and is stupidly heavy/overbuilt for FRC competition uses (like 300+ PSI).
The bigger black one looks like it's an off-road compressor tank used by off-roaders for air reserves. IE

We have used the later on 2485 to good success.
