Description and Operation
(Refer to Figure 7) Flexible hoses and aluminium tubes
(5 & 6) connect the particular components of the fuel
system. The wing tanks of the EXTRA 300/SC are equipped
with a separate drain line.
In addition to the engine driven fuel pump (3), an electrically
driven fuel pump (2) having sufficient capacity to feed the
engine at take-off power is fitted as a safety device against
failure of the engine driven pump. The electrical pump
switch is located on the instrument panel. A gascolator (4) is
installed between the fuel selector valve (7) and the electri-
cal fuel pump at the firewall (engine side). The fuel selec-
tor valve (7) is located behind the firewall on a separate
support. A control rod connects the selector valve to the
control handle. The handle has the positions "WING TANK",
"ACRO & CENTER TANKS" and "OFF".
The fuel selector valve is marked by the letters "WT" (Wing
Tank), "E" (Engine), and "CT" (Center Tanks) to ensure cor-
rect installation of fuel lines.
Drains are located at the gascolator and the left and right side
of the bottom fuselage.
