Vacuum Pump
An automotive vacuum pump is a component that is used to create a vacuum in the engine's intake manifold or brake booster system. The vacuum pump functions by drawing air out of the engine crankcase or brake booster system, which reduces the air pressure inside these components and increases their efficiency. In the case of the crankcase, the vacuum created by the vacuum pump allows for better combustion efficiency and improved fuel economy, while in the case of the brake booster system, it provides the necessary power assist for the brake pedal. The vacuum pump is typically driven by the engine's accessory belt and operates using a rotary vane or diaphragm to create the vacuum. Brake vacuum pumps are usually driven by an electric motor. A malfunctioning vacuum pump can cause a range of problems, including reduced engine performance, brake failure, or poor fuel economy. Therefore, it is important to inspect and maintain the vacuum pump regularly to ensure it is functioning properly and providing the necessary vacuum for the engine and brake system.

When choosing a vacuum pump, first determine if it will be used for brakes and other vacuum-operated components, or if it will be used in a performance or racing application for reducing engine crankcase pressure. From the remaining compatible vacuum pump options, choose the best one for your application and budget needs. For engine vacuum pumps, don't forget vacuum pump oil if applicable.
