Jeep Wrangler: VEHICLE MAINTENANCE / Draining Fuel/Water Separator Filter — Diesel Engine

The fuel/water separator housing is located inside the left frame rail in front of the fuel tank. The best access to this water drain valve is from under the vehicle.

CAUTION!

• Do not drain the fuel/water separator filter when the engine is running.
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an appropriate container.

If necessary remove the fuel filter protective cover to access the water drain valve.

2. Fuel Filter Protective Cover

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 illuminate and an audible chime will be heard. At this point you should stop the engine and drain the water from the filter housing.

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 accumulated 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.
