Fuel Tank and Vent Knob

[When using the portable fuel tank]
The fuel tank must be properly
secured in the boat. This will protect
the fuel tank from mechanical
damage caused by the fuel tank
shifting.
The fuel tank must be in a
well-ventilated area to reduce the
chance of a gasoline vapor explosion.
Avoid direct sunlight on the fuel tank.
Due to the fuel pump capacity, do not
place the fuel tank more than 2 meters
(6.6 feet) away from the outboard
motor or lower than 1 meter (3.3 feet)
below the outboard motor end fuel
(Optional equipment for BF5D and BF6A)

1. Turn the internal and portable side
fuel filler cap vent knobs 2 or 3
turns counterclockwise all the way
to open the vent.
Allow the air pressure inside the
fuel tank to equalize with the
outside air. With the vent open, air
can enter the fuel tank to displace
the fuel as the fuel level goes down.
2. Remove the fuel filler cap and
inspect the condition of the fuel
filler cap and gasket. Replace the
fuel filler cap or gasket if they are
cracked, damaged or leak fuel.
