How many electrical fuel boost pumps are on the 737?

Explanation:
Two electrical fuel boost pumps are in each fuel tank, and there are three tanks on the 737: left wing, right wing, and center wing. That adds up to six pumps in total. The pumps are placed forward and aft in each tank to ensure fuel pickup remains reliable as fuel sloshes with maneuvers or changes in attitude, and to keep the engine-driven pumps fed even if one pump fails. This redundancy is why the arrangement is two pumps per tank.
