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.
