3. EPA pressurized portable fuel tank requirements

EQUIPPED FOR UNITED STATES
AND CANADA MODEL
T h e E n v i r o n m e n t a l P r o t e c t i o n
Agency (EPA) will require portable
fuel syste m s that are pro duced
after January 1, 2011 for use with
outboard engines to remain fully
sealed (pressurized) up to 34.4 kPa
4
(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
operation 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.
REMOVING THE FUEL CAP

IMPORTANT: Contents may be under
pressure. Rotate the fuel cap 1/4 turn
to relieve pressure before opening.
①
Open the manual vent screw on top
of the fuel cap completely.
②
Turn the fuel cap until it contacts
the tab lock.
③
Press the tab lock and turn to
remove cap.

4. Fuel demand valve (FDV) requirement

EQUIPPED FOR UNITED STATES
AND CANADA MODEL
The fuel demand valve prevents
pressurized fuel from entering the
engine and causing a possible fuel
spillage. The fuel demand valve has a
manual release. The manual release
can be used (pushed in) to open
(bypass) the valve in case of a fuel
blockage in the valve.
