Which component is used to transfer fuel between any two tanks?

Explanation:
Moving fuel between tanks requires a pump to push it through the system. The boost pump provides the pressure and flow needed to transfer fuel from one tank to another, overcoming gravity and line losses so fuel can reach the engine or be balanced across tanks during flight. Cross-feed valves are just control devices that open or close pathways; they don’t move fuel themselves. A transfer line is the conduit, not the mover of fuel. Fuel transfer isn’t limited to fueling operations; it happens in flight as needed to balance tanks and maintain engine feed. So the component that actually transfers fuel between tanks is the boost pump.
