Fuel filters are essential components of a car’s fuel system, as they prevent contaminants from entering the engine and causing damage. Most modern cars have two fuel filters: a primary filter and a secondary filter. The primary filter is typically located in the fuel tank, while the secondary filter is located in the engine compartment.
The primary fuel filter is responsible for removing larger particles from the fuel, such as dirt, rust, and sediment. The secondary fuel filter further removes smaller particles, ensuring that only clean fuel reaches the engine. Both filters play a vital role in protecting the engine from damage and ensuring optimal performance.
