[Mgs] Finally got the hook

The heater valve can leak from both sides of course.  But usually closing the
valve fully will seal off the head port as tears are usually in the thinner
area of the diaphragm outside of that.  Removing the hose from the valve and
stuffing the ceramic end of a spare spark plug in the end of the hose and
putting a worm clip on it should seal off the supply from the other side of
the circuit.
