WARNING
Fuel leakage is a fire or explosion hazard, which can cause serious injury or
death.
Periodically inspect all fuel system components for leaks, softening,
hardening, swelling, or corrosion, particularly after storage. Any sign of
leakage or deterioration requires replacement before further engine
operation.
IMPORTANT: If you use gasoline that contains or might contain methanol or
ethanol, you must increase the frequency of inspection for leaks and
abnormalities.
IMPORTANT:
When operating a Mercury Marine engine on gasoline containing
methanol or ethanol, do not store the gasoline in the fuel tank for long periods.
Cars normally consume these blended fuels before they can absorb enough
moisture to cause trouble; boats often sit idle long enough for phase separation
to take place. Internal corrosion may occur during storage if alcohol has
washed protective oil films from internal components.
Low Permeation Fuel Hose Requirement
Required for outboards manufactured for sale, sold, or offered for sale in the
United States.
• The Environmental Protection Agency (EPA) requires that any outboard
manufactured after January 1, 2009, must use low permeation fuel hose
for the primary fuel hose connecting the fuel tank to the outboard.
• Low permeation hose is USCG Type B1‑15 or Type A1‑15, defined as not
exceeding 15 g/m²/24 h with CE 10 fuel at 23 °C as specified in SAE J
1527 ‑ marine fuel hose.
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.
