  • Inline Fuel Filters

    As diesel fuel generates water condensation in the fuel tank, rust particulates can be created over a period of time. An inline fuel filter can be added to the fuel line as a secondary precaution preventing contaminating particulates from getting into the fuel pump and ultimately into the injectors. In addition, if bio fuels were to be used instead of regular diesel, then the micro-organisms that are sometimes apparent in them, can be removed by the inline fuel filter.

    The inline fuel filter comes in several guises – different sizes for different pipe sizes, they can come with or without a non-return valve, and also with or without a magnet to attract any ferrous metals thus preventing any fuel contamination.

    On some vehicle applications, one fuel filter might not provide enough protection, so an inline fuel filter provides additional protection and peace of mind.
