FUEL SYSTEM
3.1 General
The fuel system used in Monterey boats is de-
signed to meet or exceed the requirements of the
U.S. Coast Guard and the Boating Industry Asso-
ciation in effect at the time of manufacture.
All fuel systems have been factory inspected and
pressure tested in accordance with regulations in
effect at the time of manufacture. This inspec-
tion 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 deterioration or loos-
ening of connections is resulting from vibration.
Fuel Tanks and Fuel Selector Valves
The fuel system has two fuel tanks and two manual
fuel valves. There is one valve for each engine
fuel supply. The fuel valves are located on the
forward bulkhead in the engine compartment. 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.
The starboard engine fuel valve is labeled “NOR-
MAL” and “PORT TANK.” The port engine fuel
valve is labeled “NORMAL” and “STBD FUEL TANK.”
The labels refer to the fuel tank the valve selects
with “NORMAL” being the port tank on the port
engine valve and the starboard tank on the star-
board engine valve. During normal operation, both
valves should be set to “NORMAL” with the port
engine being supplied fuel from the port tank and
the starboard engine supplied fuel from the star-
board tank.
If a fuel supply problem should occur in one of
the fuel tanks, the “crossover” feature
allows the
operator to select the port engine to operate from
the stbd fuel tank or the starboard engine to op-
erate from the port fuel tank.
It is extremely important that the port engine is
operated from the port fuel tank and the star-
board engine is operated from the starboard tank
to keep the boat properly balanced during normal
operation.
Fuel Withdrawal Tubes
The fuel withdrawal tubes are positioned in the
fuel tanks to achieve optimum fuel usage, fuel line
routing, 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 with-
drawal.
