and slide them away from the filter (Figure 33).
6. Place a drain pan under the fuel lines to catch
any leaks, then remove the filter from the fuel
lines.
7. Slide the fuel lines on the new fuel filter
fittings, ensuring that the arrow on the filter
points away from the fuel line coming from
the fuel tank and toward the line going to the
fuel pump.

Never install a dirty filter.
8. Move the hose clamps close to the filter.

the fuel valves.

Draining the Fuel Tank
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 tank 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.
