BOATS

FUEL SYSTEM

5.1 General

The gasoline fuel system used in Monterey boats
sold in the United States 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.

Boats sold internationally (all countries other than
the United States) are equipped with fuel systems
that are not equipped with U.S. EPA required
emission controls but do meet or exceed the re-
quirements of the U.S. Coast Guard, the Boating
Industry Association and the American Boat and
Yacht Council in effect at the time of manufacture.

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 tube is 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
various speeds of operation may occur. This sys-
tem is merely a relative indication of the available
fuel supply and not a calibrated instrument.

Fuel Fill and Vent System - U.S. Fuel
Systems

In order to comply with U.S. EPA emission regula-
tions, boats sold in the United States are equipped
with special fuel systems that do not vent directly
to the atmosphere. The system is equipped with
a “keyless” fuel cap located on the port gunnel

that is marked “GAS.” The fill cap is not vented

and the fill system is completely sealed when the

cap is closed.

There is a fuel tank vent built into the fuel fill.

Another vent equipped with vapor emission control
components in the 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
