Fuel pumps are essential components of modern vehicles, playing a critical role in ensuring that your engine receives the necessary fuel for optimal performance. At Hillside Auto Repair, we understand the significance of these components and want to shed light on how they work, their evolution, and the signs of a failing fuel pump. How Fuel Pumps Work A fuel pump is responsible for transferring fuel from the tank to the engine. It operates under high pressure, ensuring a steady flow of fuel to the engine's fuel injectors. There are primarily two types of fuel pumps used in vehicles: Mechanical Fuel Pumps: Typically found in older vehicles, these pumps are driven by the engine's camshaft and operate via a diaphragm mechanism. They draw fuel from the tank and push it to the carburetor. Electric Fuel Pumps: Most modern vehicles use electric fuel pumps. These are located inside the fuel tank and use an electric motor to pump fuel to the engine. They are more ef ... read more
