Also, certainly on the Euro models, the returned fuel is pumped around quite
a bit before it actually gets as far as the tank.  There's a thing the fiche 
calls a "gravity valve" (#161 201 753D) mounted up on top of the tank, behind
the back seat - it looks like a centrifugal de-foamer.  The return line goes
up through the bottom of the car and past the tank to the top, through the
"gravity valve" and on into the tank.  These pipes are clearly visible at the
end of the sunroof stowage - I've oftem thought it would be easy to damage
them and/or the gravity valve by carelessly shoving something big in there.
