Fuel Systems - Four winns Vista 328 Owner's Manual

I - 1 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 port and starboard fuel tanks are located forward of
the engine. See Figure I1 below. The capacity of each
fuel tank is 110 gallons for the 328 and 70 gallons for the
298. Each 298/328 Vista® is equipped with a manual
fuel valve system. This system allows you to choose
which fuel tank you want your engines to draw from and
also your generator (if so equipped). Please see Figure
I7 at the end of this section for more details.

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 Inspection Form
portion of the Warranty Registration Card will attest to
the dealer’s performance of this service.
B. Fuel Fills
The fuel fill deck plates are located on the port and star-
board rear decks and are 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 allow
water on the surrounding surfaces to run into the tank.
Periodically inspect the cap and the fuel deck plate. The
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.
Starboard Fuel Tank
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.
