Fuel is supplied from the airframe fuel tanks to the engine through which component?

The fuel pump plays a crucial role in delivering fuel from the airframe fuel tanks to the engine. Its primary function is to create the necessary pressure to move the fuel efficiently through the fuel lines and ensure a continuous and adequate supply to the engine. This is essential for the proper operation of the gas turbine engine, as it requires a specific flow rate and pressure of fuel to maintain efficient combustion and performance.

In contrast, the other components perform different functions that are vital to the fuel system's overall operation, but they do not serve the direct purpose of transporting fuel from the tanks to the engine. The fuel filter, for instance, is designed to remove impurities from the fuel before it reaches the engine, ensuring that only clean fuel is used. The fuel gauge measures the amount of fuel in the tanks, providing critical information to the pilots and maintenance teams regarding fuel availability. The fuel injector is responsible for atomizing and delivering the fuel into the combustion chamber at the right moment for efficient combustion but does not transport fuel from the tank.

Thus, the fuel pump is the correct answer as it is the component specifically tasked with moving fuel from the storage tanks to the engine for combustion.
