Abstract
Parallel transfer pumps (92, 94) operate to transfer fuel from auxiliary tanks (52, 60, 66) to the main tank (10). A pressure sensor (106) in the pump discharge line in combination with tank level rate mechanisms (86, 88, 90) sequences pumps (92, 92) and transfer valves (100, 102) if required, and confirms successful transfer or alarms when unsuccessful.
