Epa Pressurized Portable Fuel Tank Requirements - TOHATSU 40B2 Owner's Manual

3. EPA pressurized portable fuel tank requirements

EQUIPPED FOR UNITED STATES
AND CANADA MODEL
The Environmental Protect ion Agency
(EPA) required portable fuel systems
that are produced after January 1,
2011 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 two clicks. 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.
