2. Locate the module and place an
appropriate container under the
drain plug (see illustration).
3. Remove the drain plug by turning it counterclockwise. Allow to drain
for approximately 25 seconds or until clean fuel is observed. Install the
drain plug by turning it clockwise until it is firmly seated.
4. Verify that the drain plug is closed and sealed, then remove the
container from under the vehicle.
5. Restart the engine and check WATER IN FUEL indicator light; it
should be illuminated. If it continues to illuminate, have the fuel system
checked and repaired.

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
general maintenance information
section, 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.
Removal
1. Using an oil filter wrench, remove the filter.
2. Carefully clean the mating surfaces.
Installation
1. Fill the filter with clean, fresh diesel fuel.
2. Coat the filter seal with clean, fresh diesel fuel.
3. Hand-tighten the filter until it seats firmly against the mount, then
tighten (by hand) an additional
1⁄3to1⁄2turn.
4. Start the engine and check for fuel leaks.
Fuel filter replacement - 6.0L Power Stroke engine
Your vehicle is equipped with two fuel filters; one mounted on top of the
engine and the other is mounted inside the frame rail under the
driver-side floorboard near the transmission. Both filters should be
replaced at the same time.

2. Remove and discard the old fuel
filter element.
3. Carefully clean the mating
surfaces.
Installation-both
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.

Refer to your engine operator’s manual for service intervals and
procedures.
FUEL CONSUMPTION IMPROVEMENT MEASURES
There are two important factors you can control to improve fuel
economy: the mechanical condition of your vehicle and how you drive it.
A properly maintained vehicle will deliver better performance than a
neglected vehicle. Always follow your maintenance schedule to keep your
vehicle in top operating condition.
