The generator is supplied fuel from the port tank
only and uses a withdrawal tube that is shorter
than the main engine tube to prevent the genera-
tor from exhausting the reserve fuel in the tank.
Fuel withdrawal lines on gasoline fuel systems are
equipped with anti-siphon valves where the lines
attach to the fuel tank. These valves prevent
gasoline from siphoning out of the fuel tank should
a line rupture. Diesel fuel systems are not equipped
with anti-siphon valves.
IF A FUEL LINE SHOULD LEAK, ANTI-SIPHON
VALVES PREVENT A SUBSTANTIAL AMOUNT
OF FUEL FROM FLOWING INTO THE BILGE.
SHOULD AN ANTI-SIPHON VALVE BECOME
CLOGGED, CLEAN AND REINSTALL OR
REPLACE. DO NOT REMOVE THE ANTI-SIPHON
VALVES FROM THE SYSTEM. ANTI-SIPHON
VALVES ARE REQUIRED, BY THE U.S. COAST
GUARD, TO BE INSTALLED IN ALL BOATS
EQUIPPED WITH GASOLINE ENGINES.
Fuel Gauges
This indicates the amount of fuel in the tanks.
Due to the mechanical nature of the fuel senders,
variations in readings during various speeds of
operation may occur. This system is merely a
relative indication of the available fuel supply and
not a calibrated instrument.
There is a fuel gauge sender located in the top of
each tank that are connected to fuel gauges at
the helm.
Fuel Fills
The fuel fill deck plates are located on both sides
of the transom and are marked “GAS” or “Diesel.”
The fuel fill is opened by turning it counter clock-
wise with a special key. Be sure to use the proper
type and grade fuel. Refer to the engine owner’s
manual for additional information on the fuel re-
quirements for your engines.
Note: Do not over tighten the fuel cap. If the
cap is over tightened, the O-ring seal
could be damaged allowing water to
contaminate the fuel system.
DO NOT CONFUSE FUEL FILL DECK PLATES
WITH THE WATER OR WASTE FILL DECK PLATES.
THESE PLATES ARE ALSO LABELED
ACCORDINGLY. IF GASOLINE OR DIESEL FUEL
IS ACCIDENTALLY PUMPED INTO THE WATER
OR WASTE TANK, DO NOT ATTEMPT TO PUMP
IT OUT YOURSELF. WATER AND WASTE PUMPS
ARE NOT DESIGNED TO PUMP FUEL AND A FIRE
OR EXPLOSION COULD RESULT. CONTACT
YOUR DEALER OR THE MONTEREY CUSTOMER
SERVICE DEPARTMENT FOR ASSISTANCE IN
HAVING THE FUEL PROFESSIONALLY REMOVED.
Fuel Vents
There are fuel vent fittings located on each side
of the hull. While the tanks are being filled, the
air displaced by the fuel escapes through the
vents. When the tank is almost full, fuel will be
ejected from the fuel vent. You should calculate
the amount of fuel you need to avoid overfilling
the tank and ejecting fuel from the vent or fuel
fill.
After fueling, replace the fill caps, and wash the
areas around the fuel fill plate and below the fuel
vents. Residual fuel left on the hull sides can be
dangerous, and will yellow the gelcoat or damage
the striping.
3.2 Gasoline Engine Fuel Systems
The gasoline fuel system on the 350 Sport Yacht
has two fuel tanks and two manual fuel valves.
There is one valve for each engine fuel supply.
The fuel valves are located in the engine com-
partment, just below the hatch. The fuel valves
allow the operator to run the engines from either
the port tank, which fills from the port gunnel, or
the starboard tank, which fills from the starboard
gunnel.
During normal operation, the port engine should
be supplied fuel from the port tank and the star-
board engine supplied fuel from the starboard tank
(both selector valves set to the “NORMAL” posi-
tion.) If a fuel supply problem should occur in one
of the fuel tanks, both engines can be temporarily
operated from either the port or starboard fuel
tank by setting both valves on that tank. Refer to
Fuel Tanks and Fuel Selector Valves at the begin-
ning of this chapter for more information on the
operation of the fuel tank selector valves.
The fuel valves provide a means to turn off the
fuel supply to service the fuel system. Always
make sure all fuel valves are open and set to the
proper tank when the engines are operating.
