It depends entirely on how much air you need. If you're using air solely to shift gears, probably not. If every function other than drive is pneumatic, quite possibly. We blew out several hoses (with a crack like a .22) during practice for rebound rumble. We had a pneumatic climber, but we didn't even have the climber attached yet. We were just making adjustments to the Frisbee primer that required depressurizing the system. In filling up our (seven?) plastic tanks, we blew out the hose at the end nearest the compressor. The large quantity of air depressurizing through the rupture cooled the tubing back down, so it took us several swaps to figure out that it wasn't just defective tubing. This was followed by closer monitoring to figure out the actual cause. Our solution was to relocate as much of the brass as possible to before the first piece of tubing, and continued monitoring for swollen tubing.
