The need to fit extra stop-cocks (which is undesirable as their position
would not be apparent from the cockpit) can be avoided if one uses the
two-tier valve from Andair. Then the two exits from the tank would go to
this valve and the two outlets would be commoned after the gascolators.
This arrangement would also have the advantage that the drain on the
gascolator could be used to back-flush the filter by draining when the
other inlet is connected to the tank. For dismantling the gascolator
both inlets would be set to OFF.
