FUEL SYSTEM
5.1 Gasoline Fuel Systems
General
The Gasoline fuel system used in Monterey boats
is designed to meet or exceed the emission control
standards of the Environmental Protection Agency
(EPA) and the requirements of the U.S. Coast
Guard, the Boating Industry Association and the
American Boat and Yacht Council in effect at the
time of manufacture.
Notice:
This boat is equipped with an EPA compliant
fuel system. Do not alter or bypass any of
the components that are installed. See your
dealer for any fuel related service.
All gasoline fuel systems have been factory in-
spected and pressure tested in accordance with
regulations in effect at the time of manufacture.
This inspection assures that the system is air tight,
leak proof and safe. It is the responsibility of the
purchaser to maintain it in that condition. Make
frequent inspections to assure that no deteriora-
tion or loosening of connections is resulting from
vibration.
DANGER
DO NOT LET THE ODOR OF GASOLINE GO UNCHECKED.
ANY ODOR OF GASOLINE MUST BE IMMEDIATELY
INVESTIGATED AND STEPS TAKEN TO PROTECT THE BOAT
AND ITS OCCUPANTS UNTIL THE PROBLEM IS CORRECTED.
IF THE ODOR OF GASOLINE IS NOTICED, SHUT OFF ALL
ENGINE AND ELECTRICAL EQUIPMENT. INVESTIGATE
AND CORRECT THE SITUATION IMMEDIATELY. HAVE ALL
PASSENGERS PUT ON PERSONAL FLOTATION DEVICES AND
KEEP A FIRE EXTINGUISHER READY UNTIL THE SITUATION
IS RESOLVED.
Fuel Withdrawal Tube
The fuel withdrawal tubes are positioned in the fuel
tank to achieve optimum fuel usage, fuel line rout-
ing, etc. At certain speeds and hull trim angles,
the fuel supply at the withdrawal tank location can
increase or decrease accordingly. Be extremely
careful when attempting to operate the boat when
low on fuel. Though some fuel may be in the tank,
the relative trim angle of the boat may cause the
fuel to flow away from the withdrawal.
Fuel Gauge
This indicates the amount of fuel in the tank. Due
to the mechanical nature of the fuel sender and
fuel tank shapes, variations in readings during vari-
ous speeds of operation may occur. This system
is merely a relative indication of the available fuel
supply and not a calibrated instrument.
Fuel Fill & Vent System
In order to comply with U.S. EPA emission
regulations, all boats are equipped with special
fuel systems that do not vent directly to the
atmosphere. The system is equipped with
“keyless” fuel caps located on the gunnel on each
side of the swim platform that are marked “GAS.”
The fill caps are not vented and the fill system is
completely sealed when the caps are closed.
There is a fuel tank vent built into each fuel fill.
Another vent equipped with vapor emission control
components in each hull side provides ventilation
for the tank when the fuel fill system is sealed.
While the tank is being filled, most air displaced
by the fuel escapes through the fuel fill vent. The
fuel fill and vent system are designed such that an
automatic shutoff valve in the marina fuel pump
will stop the flow before fuel can be ejected into
the vent system when the tank is full. You should
never attempt to “top off” the tank after the pump
shutoff valve has activated. This could force fuel
into the vent system and damage emission control
components.
The fuel fill caps are opened by turning the cap
counterclockwise until it can be removed. After
refueling, replace the fill cap and tighten until it
clicks, indicating that the cap has been properly
closed and the fill system is sealed. Wash the areas
around the fuel fill if any fuel splashed on the deck
or hull during filling operations. Residual fuel left
on the deck and hull sides can be dangerous and
will yellow the fiberglass or damage the striping.
