Under certain conditions, fuel and fuel vapors
are highly flammable and explosive. A fire or
explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is off and
is cold. Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is to the
bottom of the filler neck.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in a clean, safety-approved
container and keep the cap in place.
3. Slide hose clamps onto ends of fuel lines. Push
fuel lines onto fuel filter and secure them with hose
clamps. Be sure arrow on side of filter points toward
the injection pump.
Fuel Lines and Connections
