Fuel System - Westerbeke 22.0 EDE 60Hz Operator's Manual

FUEL SYSTEM·
DiESEL FUEl
Use No.2-D (SAE J313) diesel fuel with a cetane rating of
#45 or higher. Grade diesel fuel according to ASTM D975.
In conjunction with Ultra Low Sulphur Diesel. Use an
additive such as Diesel Kleen
+
Cetane Boost produced by
Poirer Services (product #3025) or equivalent to help
restore fuel lubricity.
FUEL FILTERS
The fuel injection pump and the fuel injectors are precisely
manufactured and they must receive clean diesel fuel, free
from water and 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 LIFT PUMP
Periodically check the fuel connections to and out of the pump
and make sure that no leakage is present and that the fittings
are tight and secure. The DC ground connection at one of the
pump's mounting bolts should be clean and well secured by
the mounting bolt to ensure proper pump operation.
When energized thru the preheat circuit, the fuel lift pump will
purge
air
from the fuel system and provide a continuous flow
of fugl as the engine is running.
INLET FUEL FILTER
To ensure properly filtered fuel into the fuel pump, there is a
small inlet filter before the inlet to the fuel pump. Replace
this filter after the initial 50 hours of operation, then follow
the Maintenance Schedule in this manual.
A
WARNING:
·Fuel.leakage at the fuel pump or its
connections is a flre hazard and should. be co«ected.
Make sure proper ventilation exists whenever servicing
fuel system components.

ENGINE FUEL FILTER
Periodically check the fuel connections and the bowl for
leakage. Replace the filter element after the first 50 hours
then follow the
MAINTENANCE SCHEDULE.
Changing the Fuel Filter Element
Refer to the illustration.
1. Shut off the fuel supply.
2. Unthread the fuel filter from its mounting bracket.
3.
Ensure the sealing
''0"
ring comes off with the filter.
4. Apply some light oil or diesel
to
the sealing "0" ring
of the
new
filter.
5.
Thead
the
new
filter onto its mounting bracket. When the
"0" ring contacts the bracket, tighten securely.
6. Depressing
and
holding
the PRIME
button on the control
panel activates-the engine's fuel pump and primes the
system. Hold for approximatelt 20 seconds.
7. Run the engine and
inspect for
leaks.
