What role does the fuel boost pump perform?

The fuel boost pump primarily serves the critical function of transferring fuel from the collector tanks to the engines. This process ensures that the engines receive a steady and adequate fuel supply, especially during phases of high demand, such as engine start-up or sudden acceleration. By maintaining fuel flow under various operational conditions, the boost pump helps to prevent vapor lock and maintains system pressure, ensuring reliable combustion within the engines.

While other options reference important aspects of fuel management, such as heating fuel, distributing it evenly, or pumping it to auxiliary tanks, these functions are not the primary role of the fuel boost pump. Its main responsibility is to ensure that fuel is continuously supplied from the collector tanks directly to the engines, allowing for optimal engine performance and efficiency.
