Yes, the venturi generators from last year are legal as per Rule <R87>. However, they don't work in such a way that you could "pre-charge" a tank, when you open a solenoid valve letting air through them they create the vacuum, rather than having a "vacuum tank". In addition, those things are serious on the air usage, so if your going to use them for extended periods of time, you need the compressor on-board.

--NOTE-- We used them last year to pick up the tubes, worked pretty well, but the skin of that ball is going to be much harder to use vacuum cups on.
