Fuel filters collect contaminants and moisture in the fuel system to allow clean filtered fuel through to the engine. Injectors can require particles as small as 5 microns to be retained and deliver consistent performance for the entire service interval. The life of a fuel filter is dependent on the amount of contaminant present in the vehicle’s fuel. Fuel Filters are designed to improve performance by providing excellent filtration even at high flow rates thereby reducing contaminants present in the fuel to allow it to be combusted more efficiently. fuel filters utilise a special low restriction filter media that is capable of handling high GPH fuel flows.
