WARNING
!
Do not fill the fuel tank over capacity. The
rise of gasoline temperature may cause
gasoline to expand which, if overfilled,
may leak through air vent screw when it
is open. Leaking gasoline is a dangerous
fire hazard.
!
When operating a TOHATSU engine on
5
gasoline containing alcohol, storage of
gasoline in the fuel tank for long periods
should be avoided. Long periods of
storage, c ommon to boats, create
unique problems. In cars, alcohol blend
fuels normally are consumed before
they can absorb enough moisture to
cause trouble, but boats often sit idle
long enough for phase separation
to take place. In addition, internal
corrosion may take place during storage
if alcohol has washed protective oil films
from internal components.

3. EPA pressurized fuel tank requirements

EQUIPPED FOR UNITED STATES
AND CANADA MODEL
The Environmental Protect ion Agency
(EPA) will require portable fuel sys-
tems portable (after January 1, 2011)
and integral (after August 1, 2011) fuel
system for use with outboard engines
to remain fully sealed (pressurized)
up to 34.4 kPa (5.0 psi). These tanks
may contain the following:
●
An air inlet that opens to allow air to
enter as the fuel is drawn out of the
tank.
●
An air outlet that opens (vents) to
the atmosphere if pressure exceeds
34.4 kPa (5.0 psi). A hissing noise
may be heard as the tank vents to
the atmosphere. This is normal.
●
When installing the fuel tank cap,
turn the cap to the right until you
hear a click. This signals that the
fuel cap is fully seated. A built-in
device prevents overtightening.
●
The fuel tank has a manual vent
screw which should be closed for
transportation and full open for op-
eration and cap removal.
Since sealed fuel tanks are not openly
vented, they will expand and contract
as the fuel expands and contracts
during heating and cooling cycles of
the outside air. This is normal.
*Please refer to P21~26 when using this
fuel tank.
