Fuel Filter Replacement - Diesel Engine - Jeep GLADIATOR 2022 Owner's Manual

If water is detected in the water separator while the
engine is running, or while the ignition switch is in the
ON position, the Water In Fuel Indicator Light will illumi-
nate and an audible chime will be heard. At this point
you should stop the engine and drain the water from
the filter housing.
Fuel/Water Separator Filter
1 — Water In Fuel Drain Valve
Within 10 minutes of vehicle shutdown, turn the filter
drain valve (located on the bottom of the filter housing)
counterclockwise to drain fuel/water; allow the accumu-
lated water to drain. Leave the drain valve open until all
water and contaminants have been removed. When
clear fuel is visible, close the drain valve by turning it
clockwise.
Upon proper draining of the water from fuel filter
assembly, the Water In Fuel Indicator Light will remain
illuminated for approximately 10 seconds. If the water
was drained while the engine was running, the Water In
Fuel Indicator Light may remain on for approximately
three minutes.
NOTE:
Care should be taken in disposing of used fluids from
your vehicle. Used fluids, indiscriminately discarded,
can present a problem to the environment. Contact an
authorized dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
If more than two ounces or 60 ml of fuel have been
drained, follow the directions for Priming If The Engine
Has Run Out Of Fuel page 314.
