DIRECTIONS FOR USING THE PRESSURIZED PORTABLE

1. 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.
2. Open the manual vent screw on top of the cap for operation
and cap removal. Close the manual vent screw for
transportation.
3. For fuel hoses that have quick disconnects, disconnect the
fuel line from the engine or fuel tank when not in use.
4. Follow Filling Fuel Tank instructions for fueling.

Filling Fuel Tank

Avoid serious injury or death from a gasoline fire or explosion.
Use caution when filling fuel tanks. Always stop the engine and
do not smoke or allow open flames or sparks in the area while
filling fuel tanks.
Fill the fuel tanks outdoors away from heat, sparks, and open
flames.
Remove the portable fuel tanks from the boat to fill them.
Always stop the engine before filling the tanks.
Do not completely fill the fuel tanks. Leave approximately 10% of
the tank volume unfilled. Fuel will expand in volume as its
temperature rises and can leak under pressure if the tank is
completely filled.
PORTABLE FUEL TANK PLACEMENT IN THE BOAT
Place the fuel tank in the boat so the vent is higher than the fuel
level under normal boat operating conditions.
