FUEL SYSTEM INTRODUCTION
In this section, the basic fuel system components are
introduced. The fuel system includes the fuel tank, fuel
supply, fuel selector valves,
fi
ll and vent
fi
ttings along with
fuel
fi
lters and the ventilation system.
Fuel in general today is processed in a different manner
than it was a few years ago. Ethanol usually made from
corn has been added to gasoline. As a result gasoline has
become more unstable and the product shelf life has been
shortened.
As part of product features the engines and the
transmissions feature a fault handling system should a
malfunction develop. A portion of this fault system is used
to monitor the fuel system.
Select codes warn the captain with a “buzzer” sound while
others will display on the helm tachometer, display, or alarm
panel. The “pop-up” will alternate between the cause of
the fault and a task to perform to aid in eliminating the
situation.
It is important to read and understand your propulsion
owner’s manual in order to react to a fault code should
a malfunction display on the instrumentation or an
alarm sound.
Note that both Volvo and MerCruiser units used on
select vessels in the United States contain certi
fi
ed fuel
components that comply with EPA EVAP standards.
The fuel tank selector valve system regulates the fuel being
delivered via the fuel tanks. It allows you to change from
one tank to another for fuel tank equalization. There is
a generator fuel selector valve when a generator option
is installed. The generator fuel selector valve would be
another item to monitor in the fuel usage equation when
the generator is running.
See the
auxiliary equipment chapter
for further information
on the fuel selector valve system.
