(Figure 25).
6. Install a new filter and move the hose clamps close
to the filter.

fuel valve.

Draining the Fuel Tanks

In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Drain gasoline from the fuel tanks when the
engine is cold. Do this outdoors in an open
area. Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and
stay away from an open flame or where a
spark may ignite the gasoline fumes.
