FUEL SYSTEM
DIESEL FUEL
USE A DIESEL FUEL WITH A CETANE RATING OF #45 OR HIGHER.
(No. 2·0 (SAE J313) diesel fuel according to ASTM 0975}.
FUEL FILTERS
Th~
fuel injection pump and 1he fuelinjectors are precisely
manufactured and they must receive' clean diesel fuel, free
from water aiJ.d dirt. To ensure this flow of clean fuel, the fuel
must pass through at least two fuel filters, a fuel water
separator and the engine's spin·on fuel filter. Visually inspect,
clean, and change these filters according to the maintenance
schedule in this manual.
FUEL WATER SEPARATOR
A primary fuel filter of the water separating type must be
installed between the fuel tank and the engine to remove
water and other contaminants from the fuel before they can
be carried to the fuel system on the engine.
The owner/operator is responsible for making certain the
fuel reaching the engine's injection equipment is free of
impurities. This process is accomplished by installing and
maintaining a proper fuel filter/water separator between the
fuel tank and
the generator/engine. Westerbeke recommends
a 10 micron filter be used.
FUEL INJECTION PUMP
The fuel injection pump is the most important component
of the diesel engine, requiring the utmost caution in handling.
The fuel injection pump has been thoroughly bench-tested
and the owner/operator is cautioned not to attempt to service
it. If it requires servicing, remove it and take it to an
authorized fuel injection pump service facility. Do not
attempt to disassembly and repair it.
FUEL LIFT PUMP
Periodically check the fuel connections to and out of the pump
and make sure'that no leakage is present and that the fitiings
~etight
and
s~ure.
The DC ground connection at one of the
pulnp's rriouniiligbolts should be clean and well secured by
the mOunting bolt to ensure proper pump operation. "

then follbw the MAINTENANCE SCHEDULE.
Changing/cleaning the filter element
1 . . Shut off the fuel supply.
2. Unscrew the retainer ring that holds the filter bowl to the
housing and allow the bowl to come away from the
housing,
3. Remove and replace the filter element and clean the bowl.
4. Replace the sealing "0" ring and reassemble the bowl
to the housing. Thread the retainer ring on carefully
so as not to cross thread. When retainer contacts the
"0" ring, tighten 1/4 - 1/2 turns by. hand. Open the fuel
supply and run the engine to inspect for leaks.
