Answers.Text: I didn't know about gen 2.1, so I've updated my question to make it clearer. Can gen 2 pumps be used to create underpressure for the gen 1 pistons?

Body: <p>I think they are at least partially compatible, but how much so? Can generation 1 and generation 2 cylinders easily and effectively be combined in one pneumatic pipe system? I.e. a set of pipes, tubes and other parts that exchange the air and are pressurized by the same pump. And how can possible problems be overcome?</p>
