SpaceChem - Getting Pumped (1998/1/166)

This stage is ridiculous, I managed to cram everything in about 2 hours, but optimizations at this point are not easy to do...
only 6 people solved this level before me (or just uploaded it to solution.net?) so I'm quite proud of it, even though my solution is No.6 on the leaderboard (I'm not the slowest, yeah!)
