The EXTRA 300/SC has three fuel drain valves to provide for
drainage of moisture and sediment. The center- and acro tank
drain valve is located at the RH bottom of the fuselage behind
the landing gear, the wing tank drain is located at the left side.
The third drain which is interconnected to the fuel gascolator
is located in the lowest point at right side of the firewall.
D A N G E R Do not drain the fuel system when the engine or the
exhaust is hot or while the wind is strong.
A quantity of fuel must be drained prior to the first flight of
the day and at least five min. after refueling to inspect for
water and/or contamination. Continue draining each drain
valve until free of water or contamination.
I M P O R T A N T After draining, you have to be sure that the fuel drain
valve is returned to the closed position and the valve is
not leaking outside the aircraft.
