3.2 Diesel Engine Fuel System

The fuel system on your boat has one fuel tank that ﬁlls from
the starboard gunnel. The starboard engine is supplied by the
starboard fuel line and the port engine is supplied by the port
fuel line.

Diesel engines circulate much more fuel than they consume to
cool and lubricate the fuel injection system. There is a fuel
supply and return line for each engine and the generator. The
return lines return unused fuel to the fuel tank.

Proper diesel engine operation requires a good supply of clean,
dry diesel fuel.  Improper marina fuel storage techniques, lim-
ited boat usage, etc. can cause the fuel to become contaminated.
Periodically, it may be necessary to pump accumulating water
and contaminated fuel from the bottom of the fuel tank.  If
the fuel system on your boat becomes contaminated, contact
your dealer or the Albemarle Customer Service Department
for assistance.

Algae can grow in the accumulated water in diesel fuel tanks.
This condition is most prevalent in warm climates.  Periodi-
cally adding a high quality diesel fuel additive containing an
algaecide may be required to control algae in your boating area.
Please contact your Albemarle dealer or engine manufacturer
for additional information regarding fuels and additives.

Note:

Do not allow the boat to sit unused for an extended
period with the fuel tanks less than full. Changes
in temperature and weather conditions can cause
condensation in fuel tanks that are less than 3/4
full.

Diesel Fuel Filters

The diesel fuel ﬁlters are installed in the engine compartment
near the engines.  The  ﬁlters are equipped with a sensor that
will light a warning light in the helm if too much water ac-
cumulates in the ﬁlter.   A shut-off valve is located near each
ﬁlter.   The fuel line shut-off valves should always be closed
before servicing the fuel ﬁlters.

Check the ﬁlters for water before each use and replace the ﬁlter
cartridge as needed.  Water is drained from the ﬁlters by plac-
ing a cup under the ﬁlter and draining through the petcock at
the bottom of the ﬁlter until clean fuel ﬂows.  It is particularly
important to monitor the condition of the fuel ﬁlters frequently
because  diesel engines circulate much more fuel than they
consume.  Because of the volume of fuel that ﬂows through the
ﬁlters, the elements must be changed at least twice a season or
more frequently depending on the quality of the fuel and the
hours run.   Replace with a 30 micron ﬁlter cartridge and follow
the ﬁlter or engine manufacturer’s instructions for cleaning and
replacing the ﬁlter elements.

Note: Diesel fuel systems may need to be primed after

servicing. Refer to the engine owner’s manual for
information on priming the fuel system.

3.3 Generator Fuel System

The generator fuel system is much like the primary fuel engine
fuel system.  There is a fuel supply and return line to return
unused fuel back to the fuel tank.   A fuel shut-off valve  is
located on the fuel line near the ﬁlter.   The valve should always
be closed before servicing the fuel ﬁlter.

The generator withdrawal tube is shorter than the main engine
withdrawal tubes to prevent the generator from consuming the
reserve fuel. Therefore, the generator will run out of fuel if the
fuel level drops below 1/4.

A water separating fuel ﬁlter located near the generator, below
the engine compartment steps. Water is drained from the ﬁlter
by placing a cup under the ﬁlter and draining through the pet-
cock at the bottom of the ﬁlter until clean fuel ﬂows. The ﬁlter
should be checked for water before each trip and the cartridge
replaced when the main engine fuel ﬁlters are changed.
