What is the purpose of a fuel filter?

The purpose of a fuel filter is to remove contaminants from the fuel before it reaches the engine. Fuel quality and engine performance are heavily reliant on clean fuel. Contaminants such as dirt, rust, and other particulates can enter the fuel system and potentially cause damage to fuel injectors, carburetors, and other engine components. By filtering out these impurities, the fuel filter ensures that only clean fuel is delivered, thereby promoting efficient combustion and optimal engine performance. This role is critical in preventing issues such as clogging and poor fuel flow, which can lead to decreased power, increased emissions, and even engine failures.
