10 MICRON FUEL FILTER LENS3213

Function and technical context

This 10 micron fuel filter protects the injection system of your marine engine by eliminating particles, water and contaminants present in the fuel. It works in the fuel supply circuit, filtering the fluid before it reaches the injectors and the fuel pump. Its retention capacity of 10 microns is essential to avoid blockages in the injection ducts and guarantee correct fuel atomization in the combustion chambers. A defective filter allows the passage of impurities that irreversibly damage the injectors, causing loss of power, excessive consumption and poor starts.

When to replace this part?

You should change the fuel filter when you notice difficulties in starting, engine jerks under load, decreased idle speed or abnormal increase in consumption. On frequently used boats, it is recommended to inspect and replace the filter every 100-150 hours of operation or at least once per season. Preventive replacement is especially important after prolonged periods of non-use, as stored fuel tends to accumulate moisture and deposits that saturate the filter element. Changing the filter proactively avoids costly breakdowns in the injection system and guarantees reliable starts and optimal operation in any situation.
