How many fuel ejector pumps are in the Citation Longitude?

• A. Six
• B. Eight
• C. Ten
• D. Twelve

Answer: (B)

Fuel ejector pumps are used to scavenge and transfer fuel from the tanks into the engine feed system, helping maintain a reliable fuel supply under all flight conditions. In the Citation Longitude, there are eight of these pumps—four in each wing—covering the various tank compartments and the transfer path to the engines. This arrangement provides redundancy and ensures consistent fuel delivery even if one or more paths are not available, which is crucial for reliable operation with two engines and a center-tank transfer. The eight-pump setup is designed to keep fuel moving from all sections of the wings to the engines across different attitudes and loads, supporting safe, continuous operation.
