Q: What tank output pressure can I use?
A: I personally suggest buying an HP tank. The only markers that require LP tanks are specific types of Angels. HP tanks will work on just about every other gun out there.
When an LP tank is used, there is a danger of the tank not keeping up with the high rates of fire that the Shocker is capable of. Only the highest-flowing LP tanks will work without problems. This includes Guerilla Air systems, Crossfire systems, and scarce others.
