Aircraft Fuel Pumps

here are several types of fuel pumps, including Vane-type, centrifugal boost, aircraft fuel boost, Lycoming, and Jettison fuel override pumps. Each type operates differently and serves a unique purpose in getting fuel to the engine at specific steps in operation.

Fuel pumps move fuel from the tanks to the engine, ensuring a consistent and high-pressure fuel supply. They can be mechanical or electrical, with some systems designed to operate as a redundancy to prevent fuel starvation. The pump creates a suction to draw fuel and then pressurizes it for delivery to the combustion chamber or fuel injection system.

A fuel pump transfers fuel from the fuel tank to the engine, either under pressure or vacuum, ensuring the engine receives a steady flow of fuel.
