REQUIREMENTS
Regulations and Guidelines
Vessel man ufacturer, and /or inst aller of an EP A
certified outboard, must meet minimum specifica-
tions for boat fuel systems established by:
• U.S. Environmental Protection Agency (EPA)
– 40 CFR 1045.112
– 40 CFR 1060
• U.S. Coast Guard (USCG)
– 33 CFR 183
• American Boat & Yacht Council (ABYC)
– Standard H-24
– Standard H-25.
Permanent Fuel Tanks
Permanent fuel t anks mu st be pr operly ven ted
outside of the hull.
Remote fuel tank gas fills must be grounded.
Fuel tank pickups shou ld include an anti- siphon
valve to prevent fuel flo w if a le ak occurs in the
fuel distribution system.
Portable Fuel Tanks
Do not use portable fuel tanks for
outboards larger than 115 HP. Inadequate fuel
flow to high horsepower outboards can result
in serious powerhead damage.
Fuel Hose
All fuel hoses used for rigging outboards manufac-
tured after Ja nuary 1, 20 09 mu st meet EP A per-
meation requirements for evaporative emissions.
• Use SAE J30R9, or USCG Type B1-15, fuel
hose in motor well areas.
• Use USCG Type A1-15 fuel hose between per-
manent fuel tanks and motor well fittings in inac-
cessible routings.
• Compliant hoses are labeled with the applicable
specification.
Permanently installed fue l h oses should b e as
short and horizontal as possible.
Use corrosion-r esistant met al clamp s o n perma-
nently installed fuel hoses.
Multi-outboard applications require sep arate fuel
tank pickup s a nd hoses. (A fuel selector switch
may be used for “kicker” motors as long as it has
enough flow capacity for the larger outboard.)
Use only fu el line s (o r co pper t ubing) tha t me et
the Fuel Flow Requirements for the outboard.
A WARNING
If engine is equipped with a quick-discon-
nect fuel hose, you MUST disconnect the
fuel hose from the engine and the fuel tank
to prevent fuel leaks:
• Whenever the engine is NOT being used
• Whenever the engine is being trailered
• Whenever the engine is in storage.
NOTE: A small amount of fuel may be
released when the fuel connector is dison-
nected.
Store portable fuel tanks in well-ventilated
areas, away from heat sources and open
flames. Close the vent screw of the fuel
tank cap, if equipped, to prevent escape of
fuel or fuel vapors which could acciden-
tally ignite. Do not allow disconnected fuel
hoses to leak fuel.
