GASOLINE FUEL SYSTEMS

Gasoline fuel systems used in Four Winns® boats are
designed to meet or exceed the requirements of the U.S.
Coast Guard, the National Marine Manufacturers Asso-
ciation, and the American Boat and Yacht Council in ef-
fect at the time of manufacture.
Tanks on Four Winns® boats are located forward of the
aft bilge compartment below the floor. Please see the
Freedom™ or Horizon™ specifications included in your
owner's packet for fuel tank capacities or visit our
website at www.fourwinns.com.
NOTICE
Use only clean fuel of the type and grade recom-
mended by the engine manufacturer. Engine
damage resulting from the use of a lower oc-
tane gasoline is considered misuse of the en-
gine and will void the engine warranty. Refer to
the section on Gasoline Requirements in the
engine manual for information on octane specifi-
cations.
A. System Testing
All gasoline fuel systems have been factory inspected
and pressure tested in accordance with regulations in
effect at the time of manufacture. Additionally, each fuel
tank must pass rigid tests and inspections performed by
the fuel tank manufacturer.
Prior to taking delivery, it is important that a full inspec-
tion be made of the entire fuel system by the selling
dealer. An entry on the Four Winns® Pre-Delivery In-
spection Form portion of the Warranty Registration Card
will attest to the dealer's performance of this service.
B. Fuel Fills
Fuel fill deck plates are located either on the aft deck or
side decks, and are marked "GAS". To open, insert the
deck plate key into the holes on the cap and rotate coun-
terclockwise. A bead chain connects the cap to body
to help prevent loss overboard. Be sure to utilize the
proper type and grade of fuel as recommended by the
engine manufacturer. See Section I-3 for additional infor-
mation.

FUEL SYSTEMS

The fuel fill fitting allows for venting below the fill cap.
While the tank is being filled, the air displaced by the fuel
escapes through the fuel fill/vent. This reduces the
amount of fuel spillage. Always open the lid slowly to
allow air to escape. See Figure I1.
The gasket seal on the fuel fill cap assists in sealing
when closed. A missing or damaged gasket can allow
water on the surrounding surfaces to run into the tank.
Periodically inspect the gasket and the fuel deck plate
for damage.
DO NOT confuse GAS deck fill plate with WA-
TER or WASTE deck plates. Deck fill plates
are labeled according to the intended use.
Spilled fuel is a fire hazard. DO NOT overfill or
overflow the tank, or allow fuel spills into the hull
or bilge. If spillage occurs, clean up immedi-
ately and dispose of soiled rags/towels in a pro-
per container.
When fueling at a marina, DO NOT overfill. Fuel
may spill into the water.
Check Valve prevents
spills from fuel surge.
Baffles allow air ventilation
but trap water
Splash Shield sends overflow
from vent back to tank
