It looked so simple at first!

I worried about that at first as well. I suppose you could always use a vacuum pump to put the booster under vacuum before fitting, if you really wanted to. I got lazy and just fitted it straight up with no vacuum. I figured I'd give it a try and see if it needed more adjustment after it was running. Doesn't seem to.
