Center Fuel Tank Pump Switches

Center Fuel Tank Pump SwitchON - ON is indicated when all lights are extinguished on the center fuel tank pump switches.

FAULT - The amber FAULT light comes on when the associated center tank pump is in operation and the delivery pressure drops to less than normal.

If MODE SEL switch is selected to MAN, the associated center tank pump is activated regardless of flap position or fuel quantity.

If MODE SEL switch is selected to AUTO this allows automatic operation of the center fuel tank pumps.

If the center tank is supplying fuel, the wing tanks tend to overfill; therefore, the center tank pump is automatically selected off when the inner WING tank is full. The wing tank supplies the engine fuel until approximately 1100 pounds of fuel is used, and then the center tank pump resumes operation.
