Then unscrew the fuel filter housing located on the bottom of the valve
(see pictures below). After unscrewing the housing, remove the filter
from it and clean it (for example, rinse in gasoline and blow off under low
pressure). Install the filter in the reverse order of removal, also
remembering to fit the ring gasket.
Some models are equipped with an additional fuel filter mounted on the
fuel hose (see the image below). Prior to change it drain the fuel form the
tank, carburetor and line, than remove it from the hose by loosening the
clamps on the hoses on both sides of the filter and gently pulling and
rotating one side of the filter from the hose. Repeat this on the other side
of the filter. Remember the correct direction of the filter (fuel flow)
before installing the new filter on the fuel hose.
