What is a fuel pump? The fuel pump is the core power component of the fuel supply system in internal combustion engine-powered equipment such as automobiles, trucks, motorcycles, and generators. Its core function is to draw fuel from the fuel tank and, through an internal pressurization mechanism, stably deliver the fuel to the engine (or injection system), providing continuous fuel that meets pressure and flow requirements for combustion under different operating conditions such as idle, acceleration, and high load. It is a key device for ensuring the engine's power output, fuel economy, and operational stability. .
