Re: MB Ur-questions

["Jouko Haapanen" <joukoh@vtoy.fi>]

I was looking at that wonderful vacuum hose art on the underside of the
hood earlier today - hence the questions.  The nipple pointing directly to
the clouds (ie. vertical/upwards) is presently unoccupied on the WGFV.  The
hose off the top of the WG belongs here?  Ok, but some knob has shortened
the hose (actually 200mm) or at least it won't reach.  Oh well, I'll fix
that tomorrow.

BTW, what happens (or seizes to happen) when it is disconnected?
