[Vwdiesel] Derek's a water geezer

[Derek]

A hobbs switch is just a type of pressure switch.  It is relatively
inexpensive and should be available from most auto parts stores.  The
pressure signal comes from just about anywhere you'd like.  I teed it from
the line that goes from the intake tube to the fuel pump.  You just set the
hobbs switch to come on at a pressure of your choosing, I set mine at about
7psi.
