WATER SEPARATING FUEL FILTER (NOT INCLUDED WITH

1 A water separating fuel filter is not included with your engine but
is recommended. This filter removes moisture and also debris
from the fuel and should be mounted before the fuel pump sup-

water can be removed and the filter reused. If the filter becomes
plugged with debris, the filter must be replaced with a new filter.
Remove and replace filter as follows
a. Turn ignition key switch to OFF position.
b. Remove filter by turning the filter in the direction of the arrow
indicated above (counterclockwise). Tip the filter to drain fluid
in a suitable container.
c. Lubricate the sealing ring (c) on the filter with oil. Install the
filter and tighten securely by hand.
IMPORTANT: Visually inspect for fuel leakage from the filter af-
ter starting the engine.
