Operators Manual

Table Of Contents
NOTE: If you are replacing all fuel filters, it is not necessary to run the
engine and test for leaks after installing each individual fuel filter. However,
if repairing a leak at one filter, complete that repair and test the system for
leaks after priming the fuel system.
Filters are an integral part of the fuel system. Proper filter selection and
maintenance are important to satisfactory engine operation and service life. Filters
should be used to maintain a clean system, not to clean up a contaminated system.
The scheduled maintenance intervals for the appropriate duty cycles are listed in
this manual.
WARNING: PERSONAL INJURY
To prevent the escape of high pressure fuel that can penetrate
skin, ensure the engine has been shut down for a minimum of 10
minutes before servicing any component within the high pressure
circuit. Residual high fuel pressure may be present within the
circuit.
NOTICE: At cold temperatures (-40° C or -40° F), DO NOT remove the filter
elements from the caps unless the intent is to replace the filter elements.
Repeated removals at cold temperatures may break the filter element tabs.
Removal of the Fuel Prefilter - Two-Filter System
Remove the prefilter as follows:
1. Using a 36 mm socket, unscrew the prefilter cap.
2. Pull the cap and prefilter straight up and out of the fuel filter housing.
