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.
The fuel tank on Vista models is located forward of the
engine. Refer to Table I below for fuel tank capacities by
model.

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 Service Record will attest to the dealer's
performance of this service.
B. Fuel Fills
Fuel fill deck plates are located on the starboard rear
deck on all Vista models and are marked FUEL or GAS.
Be sure to utilize the proper type and grade fuel. Refer to
the fuel information on page one in this section.

DO NOT confuse FUEL deck fill plate with WA-
TER or WASTE deck plates. Deck fill plates are
labeled according to the intended use.
The o-ring seals on the fuel fill cap assist in sealing 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, if so equipped, should be inspected for cracks
or damage and replaced as necessary. Lubricating with
a light, water-proof 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 overfill or overflow the tank, or allow fuel
spills into the hull or bilge.
After fueling, replace the fill cap, and wash the areas
around the fuel fill plate and below the fuel vent. Residual
fuel left on the deck and hull sides can be dangerous,
and will yellow the fiberglass.
Periodically, remove the caps from the fuel vent, clean
the vent of any dirt, wax, etc. Be sure the cap is replaced
securely after cleaning. The vents are designed to keep
insects and foreign matter from contaminating the fuel
and fuel system.
