Filling the Fuel Tank
NOTICE: Operate bilge ventilation
(blowers) for a minimum of 5 minutes to
purge fumes from engine compartment after
refueling. Never operate bilge blower while
refueling. Doing so can pump explosive
fumes into the engine compartment and
result in an explosion.
To Fill the Fuel Tank:
NOTICE: Only fill the fuel tank with diesel
fuel. Filling the fuel tank with gasoline may
result in a fire and will damage the engine.
1. Clean the area around the fuel cap.
2. Remove the fuel cap from the fuel tank
filler port.
3. NOTICE: Hold the hose nozzle firmly
against the filler port while filling. This
prevents static electricity buildup which
could cause sparks and ignite fuel
vapors. Stop fueling when the gauge
shows the fuel tank is full. NOTICE:
NEVER overfill the fuel tank.
4. Replace the fuel cap and hand-tighten.
Over-tightening the fuel cap will
damage it.
Bleeding the Fuel System
The fuel system needs to be bled under the
following conditions:
• Before starting the engine for the first time.
• After running out of fuel and fuel has been
added to the fuel tank.
• After fuel system maintenance, such as
changing the fuel filter and draining the fuel
filter / water separator, or replacing a fuel
system component.
The fuel feed pump is ECU-controlled and
will operate for only 10 seconds when the
key switch is turned ON while the engine is
not running or being started. For this reason,
the key switch must be repeatedly turned
ON then OFF to sufficiently bleed the fuel
system.
1. Turn the key switch on and leave on for
10 seconds. NOTICE: NEVER hold the
key in the START position for longer
than 10 seconds or the starter motor will
overheat.
2. Turn key switch OFF for 5 seconds, then
turn key switch ON for 10 seconds.
3. Repeat steps 1 and 2 five more times.
Note: The engine may run rough and misfire
for a few seconds when first started until any
remaining air is purged from the fuel system.
4. Attempt to start the engine. If the engine
does not start within a reasonable time,
repeat steps 1 and 2 until the engine
starts and runs. NOTICE: NEVER use
an engine starting aid such as ether.
Engine damage will result.
