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.
NOTICE
Use only clean, dry fuel of the type and grade
recommended by the engine manufacturer. The
use of incorrect or contaminated fuel can cause
engine malfunction and serious damage. En-
gine damage resulting from the use of a lower
octane 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.
The fuel tank is located forward of the engine. See Fig-
ure I1 below. The capacity of the fuel tank is 70 gallons
for the 248 and 85 gallons for the 268.

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.

FUEL SYSTEMS
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
The fuel fill deck plate is located on the starboard rear
deck and is marked "GAS". Be sure to utilize the proper
type and grade fuel. Refer to Section I-3 for information
regarding fueling instructions.
The gasket/o-ring seals on the fuel fill cap assist in seal-
ing when closed. A missing or damaged o-ring can al-
low water on the surrounding surfaces to run into the
tank.
Periodically inspect the cap and the fuel deck plate. The
Fuel Fill
o-ring seal should be inspected for cracks or damage
and replaced as necessary. Lubricating with a light, wa-
terproof oil or grease is recommended and can extend
the o-ring's longevity.
C. Fuel Vents
The fuel tank is vented overboard. While the tank is
being filled, the air displaced by the fuel escapes through
the vent. When the tank is almost full, fuel will be ejected
from the fuel vent.
DO NOT confuse FUEL 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 and explosion hazard. DO
NOT overfill or overflow the tank, or allow fuel
spills into the hull or bilge. If spillage occurs,
clean up immediately and dispose of soiled rags/
towels in a proper container.
NOTICE
When fueling at a marina, DO NOT overfill. Fuel
may spill into the water.
