Notes on Fuel System
The illustration that follows is an exploded view
of
a typical fuel system for 4-cylinder diesel-engine gener-
ators. The figure also illustrates the self-bleeding and priming system used
by
Westerbeke.
The Westerbeke self-bleeding fuel system is semiautomatic in operation. While it is unlikely that the operator
will be forced
to
service the system at sea, the possibility does exist. Therefore, it is recommended that banjo
washers, injector seat washers, electric
lift pump filter and gasket, fuel filter and gasket be carried on board
at
all times. Select the parts
for
your engine from the Parts List and purchase spares from
your
local Wester-
beke Dealer
or
Distributor. For example, a fuel system hardware kit that contains sealing washers
for
on-en-
gine fuel system components should be purchased.
If a leak should develop at a fuel banjo
or
sealing washer location and cannot be corrected
by
a simple
tightening
of
the fitting, replace the washers with one
of
those in the kit.
Replacing Filter Elements
After the first 50 hours of operation, replace the filter element located in the base
of
the electric fuel pump.
Remove the fuel pump's base using an open end wrench. Take care in catching the filter element and fuel
within the pump.
Install a new element and sealing washer for the base. Ensure that the magnet is located
in the center of the base, and then
reinstall the locking base onto the securing pins at the base of the pump.
This same service is required
of
the secondary fuel filter. This filter is a spin-on type. Simply unscrew the fil-
ter and replace it with a new cartridge. Take care in catching any fuel that may be spilt while removing the
cartridge.

After the first 50-hour change, the change period may be increased
to
200 hours
or
once per season. Good
quality fuel filter/water separators
installed along the fuel supply line between the fuel tank and the gener-
ator's engine, and which are serviced regularly, will increase the service life of the on-engine filters.
