Observe all safety precautions required when handling
gasoline. Fill the fuel tanks through the filler located on the
forward slope of the wing. Each wing holds a maximum of 60
U.S. gallons. When using less than the standard 120 gallon '-""'
capacity, fuel should be distributed equally between each side.
NOTE
Aircraft should be refueled in a wing level
condition. At times this will require alternate
filling of left and right tanks until the full
condition is reached.
(d) Draining Fuel Strainer, Sumps and Lines
The fuel tank sumps and filter should be drained before the first
flight of the day and after refueling. Set fuel selector on left or right
tank before draining. The fuel collector/sump tanks, located at the
root of each wing. are the lowest points in the system. Each tank
drain is accessible through a hole in the bottom wing skin adjacent
to the wheel well. The fuel filter drain is located on the right hand
side of the fuselage several feet forward of the wing. Sumps and
~
filter should be drained until sufficient fuel has flowed to ensure the
removal of any contaminants. When draining sumps. use the end on
sampler cup to push in valve, catching fuel in the cup. (Refer to
Figure 8-3) To drain filter, hold sampler cup under nylon tube and
push in tube. Always inspect fuel for contaminants, water and fuel
grade (color). Assure that valves have sealed after draining.
NOTE
Sump drains will lock open if valve is pushed in
and turned. Continue turning to release lock.
