GASOLINE FUEL SYSTEMS
Gasoline fuel systems used in Four Winns
designed to meet or exceed the requirements of the
US Coast Guard, the National Marine Manufacturers
Association, and the American Boat and Yacht Coun-
cil in effect at the time of manufacture.
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. Engine damage resulting from the
use of a lower octane gasoline is considered
misuse of the engine and will void the engine
warranty. Refer to the section on Gasoline
Requirements in the engine manual for
information on octane speciﬁcations.

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 per-
formed by the fuel tank manufacturer.
In twin engine applications, the port and starboard fuel
tanks are located forward and outboard in relationship
to their respective engine. See Figure I1. The capacity
of the fuel tank(s) may be found on our website at
Prior to taking delivery, it is important that a full
inspection 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 perfor-
mance of this service.
The V335 models are equipped with twin fuel tanks
and come with a manual fuel valve system.
B. Fuel Fills
See Figure I2. This fuel valve system allows you to
manually select which fuel tank you want your engines
to draw fuel from. The generator (if applicable) uses a
separate fuel pick-up. Please see Figure I8 at the end
of this section for fuel valve operations.
The fuel ﬁll deck plates are located on the port and
starboard rear decks and are marked “GAS”. See
Figure I3. Be sure to utilize the proper type and grade
of fuel as recommended by the engine manufacturer.
To open, insert the deck plate key into the holes on
the cap and rotate counterclockwise. A bead chain
connects the cap to body to help prevent loss over-
board. Refer to Section I-3 for information regarding
Port & Stbd
