Located just below the engine, a fuel filter is a device that sieves out unwanted contaminants from fuel. It's a simple device that helps to improve fuel efficiency. A fuel filter also helps to protect the engine nozzle and the engine injection pump.

A fuel filter can be located under the vehicle body, on the gas tank, or on the fuel injector assembly. It's important to clean the fuel filter regularly. Fuel filters should be replaced at least once a year to avoid damage.

A fuel filter is a vital component in a vehicle's fuel system. It helps to keep the fuel clean and free of contaminants, which can affect performance and profitability.

Fuel filters are typically made from steel, metal, or plastic. Most filters use hose barbed inserts to hold the filter media in place. Some filters require special tools to remove.

The filtering medium of the fuel filter is usually polyester or cellulose. It is a porous material that helps to trap impurities in the fuel.
A water separator is typically included in the fuel filter to help separate water from foreign particles in the fuel. A water sensor is also included to alert the driver when the water needs to be drained. The filter is rated to 10 microns.
