The engine driven fuel boost pumps are driven by ___?

Explanation:
Engine-driven fuel boost pumps are powered through the engine’s accessory gearbox, and that gearbox is driven by the gas generator section, Ng. This setup means the pumps receive drive in proportion to Ng, which keeps fuel pressure available during start and operation. The high-pressure (HP) spool and the N1 (core) spool are not used to drive the accessory gearbox in this engine configuration, and the Fuel Pump Drive is the component that transmits power to the pumps rather than the source of that power.
