EPA PRESSURIZED PORTABLE FUEL TANK REQUIREMENTS
The Environmental Protection Agency (EPA) requires 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).
FUEL DEMAND VALVE (FDV) REQUIREMENT
Whenever a pressurized fuel tank is used, a fuel demand valve is required to
be installed in the fuel hose between the fuel tank and primer bulb. The fuel
demand valve prevents pressurized fuel from entering the engine and causing
a fuel system overflow or 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.
a - Fuel demand valve ‑ installed in the
fuel hose between the fuel tank and
primer bulb
b - Manual release
c - Vent/water drain holes
FUEL TANKS
Portable Fuel Tank
Select a suitable location in the boat within the engine fuel line length
limitations and secure the tank in place.
Permanent Fuel Tank
Permanent fuel tanks should be installed in accordance with industry and
federal safety standards, which include recommendations applicable to
grounding, anti‑siphon protection, ventilation, etc.
FILLING THE FUEL SYSTEM
When starting an engine for the first time, or starting an engine that ran out of
fuel or was drained of fuel, fill and prime the fuel system.
To fill and prime the fuel system:
1. Squeeze the fuel line primer bulb until it feels firm.
2. Turn the key switch to the "ON" position for three seconds. This operates
the electric fuel pump.
3. Turn the key switch back to the "OFF" position and squeeze the primer
bulb again until it feels firm.
