SP8-10. FUEL FILTERS
1. Your engine or generator set should have a primary
fuel filter installed. We recommend the Racor brand
of fuel filter - water separators.
a. Check the primary fuel filter daily as recommended
by the filter manufacturer. Empty the collection bowl
as necessary.
b. Change the element every 500 hours or whenever
necessary.
c. If the bowl fills with water, change the primary
and secondary elements immediately.
2. Change secondary fuel filter every 500 hours.
NOTE: The fuel filter on the engine is considered the
“secondary fuel filter”. The engine will be fitted with a
quick change disposable secondary fuel filter.
CAUTION: Serious injury can result from escaping
high pressure fluid. Relieve pressure before
disconnecting fuel or other lines. Before applying
pressure, tighten all connections. Do not use your
hand to search for leaks - use a piece of cardboard
or paper. Gangrene could develop if fluid is
accidentally injected into the skin, a doctor needs to
surgically remove the fluid within a few hours of the
accident.
a. Turn off the fuel.
b. Clean filter assemblies and surrounding areas.
Disconnect the water sensor wiring, if equipped.
Servicing
Figure 11: Filters
c. Loosen the filter drain plug on the bottom and
drain the filters.
d. Remove the filter by turning the filter clamp on
the top, while lifting up on the clamp while it is
turning
,
counter clockwise until the filter
cartridge slides out.
e. Remove water separator element by unscrewing
the sediment bowl.
NOTE: Before installing a new filter cartridge make sure
the surfaces where the cartridge comes in contact with
the mounting plate are absolutely clean. Dirt can be
washed into the fuel injection system. This may result
in severe damage to the fuel injection pump or nozzles.
Do not “prefill” the new fuel filter as the fuel used
may be contaminated and damage the fuel system
components.
f. Install new filter cartridge and separator unit.
g. Both fuel filter and water separator elements are
supplied in the fuel filter service kit RE527961.
Elements are not available separately.
h. Turn on the fuel.
