The fuel pumps are AC powered.
Two fuel boost pumps are located in each tank. One pump is located forward, and the other is located aft to provide positive fuel pressure at all times. Separate 115V AC buses power pumps in the same tank, failure of any one bus affects only one pump in any given tank.
The APU, however, has a DC fuel pump so it can be started off the aircrafts batteries. This DC pump is located in the #2 main tank. After the battery start is complete, and the APU is running, fuel is supplied by the #2 main tank aft AC pump. The DC pump shuts off after the AC pump takes over. Fuel to the APU can be supplied from any tank except reserves, if needed, through the #2 crossfeed valve.
