Typical EPA Fuel System
Typical Fuel Tank
Vessels manufactured for domestic use are now
required to be outfitted with an EPA compliant
fuel system topically using an aluminum tank that
must pass a battery of tests. This system uses
special valves and baffles located inside the fuel
tank along with special hoses marked for low
permeability. Also, there is a carbon canister in-line
with the vent hose which functions much like the
one in an automobile by filtering gas fumes. The
carbon canister rarely needs to be replaced and is
not a serviceable item.
These tanks are tested and inspected along with
the complete fuel system several times for safety
requirements and quality by the fuel tank supplier,
in house personnel and independent inspections
by National Marine Manufacturers Association
personnel.
Fuel Fill Fitting
The fuel fill fitting is labeled “gas” and in addition
displays the international symbol (See the next
page). When fueling the boat keep the fill nozzle
in contact with the fuel fill pipe since it decreases
effects of static electricity. Always use the
recommended fuel octane rating as specified in
your engine owner’s manual.
Extinguish all flame producing agents before fueling!
