A mechanical fuel pump operated by a belt connected to the engine’s crankshaft is a common component in many internal combustion engines, particularly older vehicles and some specialized applications. This type of pump utilizes the engine’s rotational energy to create pressure, drawing fuel from the tank and delivering it to the carburetor or fuel injectors.
This method of fuel delivery offers several advantages, including simplicity, reliability, and relatively low cost. Because these pumps are mechanically driven, they do not require electrical power and are less susceptible to electronic failures. Historically, this type of pump was the standard for decades, offering a robust and efficient solution for fuel delivery in a range of vehicles. Its enduring presence in certain applications highlights the continued practicality of this established technology.
