Fuel pump and filter..?

A fuel pump is a mechanical device that pressurizes and sends fuel from a fuel tank to an internal combustion engine. The fuel pump may be placed inside the fuel tank or externally, near the engine. In an external fuel pump, a filter is usually installed between the fuel tank and the fuel pump to prevent dirt and debris from entering the pump. This filter is often referred to as a fuel strainer or fuel filter.

The purpose of the fuel pump is to provide a constant flow of fuel to the engine. The fuel pump is driven by the engine, either directly or through a belt or chain. When the engine is running, the fuel pump draws fuel from the fuel tank and pressurizes it. The pressurized fuel is then sent to the fuel injector or carburetor, which mixes the fuel with air and delivers it to the engine's cylinders.

Fuel pumps are available in various designs, including mechanical, electric, and electronic fuel pumps. Mechanical fuel pumps are driven by the engine's camshaft or crankshaft. Electric fuel pumps are powered by an electric motor, while electronic fuel pumps are controlled by an electronic control unit (ECU).

Fuel filters are used to remove impurities and contaminants from fuel. Fuel filters are typically made of paper or cloth and are installed in the fuel line between the fuel tank and the fuel pump. Fuel filters help to protect the fuel system components from damage and can extend the life of the fuel pump and other components.

Fuel pumps and fuel filters are essential components of the fuel system and play a critical role in ensuring the engine receives a constant flow of clean fuel.
