Took me a while to figure the heavy engine breathing was something other than a piston down.
The box on the governor provides modulated vacuum to the gearbox to soften the gearchange.

But if you simply plug it you will lose the IP shut-off, door locks, headlight levelling etc that operate by vacuum with the shut-off being the most vital. There has to be a loose line somewhere that plugs into the pump spigot. As an aside, and although it may only apply to a 606 motor, when I inadventantly left a line open the crankcase heavily overpressurised. The pump exhausts it's vacuum directly into the crankcase. This event doesn't normally happen because once vacuum is drawn the pump effectively freewheels, but if a line is left off it continues endlessly pumping.
