Final answer:
In an aircraft, the Transfer Ejector is the component that moves fuel from the auxiliary tanks to the main tanks.
Step-by-step explanation:
The ejector responsible for moving fuel from the auxiliary tanks to the main tanks in an aircraft is known as the Transfer Ejector. The scavenge ejector typically serves to ensure that fuel does not remain in an auxiliary tank after transfer, the main ejector pumps fuel to the engines, and the auxiliary ejector is typically involved in transferring fuel between tanks but not necessarily into the main tanks.
