Note: The No. 1, No. 2, and center tank refueling valves each have a red
override button that must be pressed and held while fuel is being
pumped into the tank. Releasing the override button allows the
spring in the valve to close the valve. A tool may be required to
hold the spring in the valve to the OPEN position.
Caution must be observed not to overfill a tank, since there is no
automatic fuel shut-off during manual operation. When the
desired amount of fuel has been pumped into the tanks, the
refueling valves for the respective tanks can be released. Tanks
No. 1 and No. 2 may also be refueled through filler ports over the
wing. It is not possible to refuel the center tank externally using
overwing ports.
