Strainers pick the fuel up from the right and left wing tanks. Fuel is
then routed through pipes to the fuel selector valve and then to the
gascolator (fuel filter). The gascolator is located on the lowest point of
the engine side fuel system, which can be drained there.
The fuel is then routed to the electrically driven fuel pump. This pump
is bypassed with a check valve.
