Fuel system Fuel Filter The life of the filter depends on the amount of impurities it is required to remove from the fuel. Therefore, clean fuel will not only increase the life of the filter element, but also make it more efficient. Spin-On type paper filter element is fitted in the fuel filtration system as original equipment. Filter element should not be cleaned but only replaced every 100 hrs of operation or earlier if required. If impaired, engine operation indicates the filter has become clogged, replace the filter element immediately. This condition will be indicated by loss of power and engine misfiring at full load.
