Fuel system questions

[Fergus Kyle <VE3LVO@rac.ca>]

Cheers,
            I have both mod 33 water drains under the expanded baggage bay
and below the tank, and gascolator just after the pump enroute the engine
(Mark 1 foam wings, XS cockpit).
            I have always considered the drains as detecting/ridding the
hangared tank of stagnant water or waterborne FOD, and the gascolator of
catching the rest of the system before engine entry and enroute. It's a way
of catching a bad fuelstop - we have some longterm stored fuel stops here.
Happy Landings
