The fuel filter is installed on the fuel line between the fuel pump and the carburetor and should be changed every 20,000 km. When replacing the filter, clamp the fuel hoses suitable for it with clamps to prevent fuel from escaping. Remove the clamps from the hoses and disconnect them from the filter. When installing a new filter, make sure that the arrow with which the filter is marked points in the direction on which the carburetor is installed. Put on and tighten the hose clamps and remove the clamps. The filter ventilates itself.
