Fuel Fills - Four winns V458 Owner's Manual

B. Fuel Fills
The fuel fill deck plates are located on the port and
starboard at the transom and are marked "DIESEL".
See Figure I2. Be sure to utilize the proper type and
grade of fuel as recommended by the engine manu-
facturer. 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
overboard. Refer to Section I-2 for infor mation regard-
ing fueling instructions.

(Port & Stbd Typical)
DO NOT confuse FUEL deck fill plate with
WA TER or WASTE deck plates. Deck fill
plates are labeled according to the intend ed
use.
The gasket/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 should be inspected for cracks or
damage and replaced as necessary. Lubricating with
a light, waterproof oil or grease is recommended and
can extend the O-ring's longevity.
C. Fuel Vents
On the V458 separate thru-hull fuel vents are in-
stalled. See Figure I3. While the tank is being filled,
the air displaced by the fuel es capes through the vent
overboard.

Fuel Fill
Spilled fuel is a fire and explosion haz ard. DO
NOT ove rfill or ove rflow the tank, or al low fuel
spills into the hull or bilge. If spill age oc curs,
clean up im me di ately and dis pose of soiled
rags/towels in a pro per con tain er.
When fueling at a marina, DO NOT over fill.
Fuel may spill into the water.
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 fiber glass. It will also
damage the tape stripes and logos.
For those models with thru-hull venting, periodically,
inspect the fuel vent(s) for any dirt, wax, etc. Carefully
remove any obstruction with a pipe cleaner or similar
device. Be sure not to puncture the screen. The
vent screens are designed to keep insects and foreign
matter from contaminating the fuel and fuel sys tem.
The stainless steel cap is not removable.
Figure I3: Port Fuel Vent Location
(Port & Stbd Typical)
Avoid overboard spills. When tank is
almost full the sound from the fuel vent
will change. The pitch will become
higher indicating the tank is close to
being full. Stop pumping fuel into tank.
Do not top off.
