REPLACING THE FUEL FILTER
See Table 3-1 for scheduled fuel filter replacement.
A dirty fuel filter may be the cause of a failure to start.
The fuel filter is accessible through the front access
door (Figure 3-4).
WARNING
Diesel fuel is combustible and can
cause severe personal injury or death. Do not
smoke near diesel fuel tanks or equipment.
Keep flames, sparks, pilot lights, electrical
switches, arc-producing equipment and all oth-
er sources of ignition well away. Keep a type
ABC fire extinguisher in the vehicle.
Close any fuel line shutoff valve before discon-
necting the fuel line from the filter.
Accidental or remote starting can cause severe
personal injury or death. Disconnect the nega-
tive (−) cable at the battery to prevent starting
while working on the genset.
Removing the Fuel Filter
Use paper towels to clean the two fuel hose fittings
and absorb any fuel that spills. To disconnect the
hoses, use a flare nut wrench on the hose flare nuts,
so as not to round the corners, and a second wrench
on the filter fitting, so as not to stress the fitting. (Re-
moving the bracket screws first will make the job
easier.)
CAUTION
Dirt can damage the fuel system.
Make sure to wipe dirt off the fuel hose fittings
before disconnecting.
Dispose of the fuel filter and paper towels in accor-
dance with local regulations.
Installing the Fuel Filter
Rotate the filter half a turn around its mounting stud
if the fittings interfere with the bracket. It only fits one
way.
Connect the fuel fittings before tightening the filter
mounting nut. Take care not to crossthread the fuel
fittings. Thread them in by hand and tighten one flat
past seating with two wrenches.
Prime the fuel system for half a minute to fill the new
filter with fuel and then secure the access door.
