FUEL FILTER/WATER SEPARATOR
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
The fuel filter/water separator removes any contaminated particles
and/or water from the fuel before the fuel enters the engine.
The fuel filter/water separator should be drained as recommended in the
Scheduled Maintenance Guidechapter.
DRAINING THE FUEL FILTER/WATER SEPARATOR – 6.0L POWER
STROKE ENGINE
Water should be drained whenever
the warning light comes on or every
5,000 miles (8,000 km).
1. Stop the vehicle andshut offthe engine.
2. Locate the drain valve and place
a suitable container at the end of
the drain tube.
3. Turn the drain valve to the drain position and allow water to drain out.
Note:Drain until the water/fuel mixture becomes only fuel.
4. Turn the drain valve to the closed position.
5. Restart the engine and check WATER IN FUEL indicator light; it
should not be illuminated. If it continues to illuminate, have the fuel
system checked and repaired.

INSTALLATION
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install new fuel filter into the fuel filter housing.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
After replacing the fuel filter, the engine will purge the trapped
air as it runs. The engine may run roughly and smoke until the air
is completely eliminated.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
FUEL FILTER REPLACEMENT - CUMMINS B ENGINE
Refer to your engine operator’s manual for service intervals and
procedures.
FUEL FILTER REPLACEMENT - CATERPILLAR ENGINE
The fuel filter/water separator is
located on the left side of the
engine. Replace the fuel filter/water
separator as recommended in the
Scheduled Maintenance Guide
chapter, or sooner if it becomes
plugged. Vehicles operated on fuel
with more than average impurities
may require replacement of the fuel
filter more frequently. The spin-on
filter has a water drain valve built
into the bottom of the filter canister.
