[Mgs] Gas anti siphon spring headache.

[Paul Hunt]

Are you sure about that?  If so they are very different to the ones used in 
the UK.  We don't have the plastic seal to recover the vapours as fuel is 
pumped in, but we still have an auto shut-off (and they still shut-off when 
they shouldn't).  There is a very small pipe inside the main pipe and when 
that gets splashed with fuel it trips the shut-off mechanism inside the 
handle.
