3. Place a fuel-resistant container under the fuel filter.
The filter drain valve is located in the engine, on the
passenger’s side of the vehicle, on the bottom of
the fuel filter.
4. Open the drain valve
by turning two to three
turns. When fuel
empties from the valve,
all the water has
been drained. Close
the valve hand tight.
To help remove all
the water, press
the priming pump
several times.
5. Remove the fuel-resistant container and properly
dispose of the contaminated fuel. To find out how
to properly dispose of contaminated diesel fuel, see
“What to Do With Used Oil” under Engine Oil on
page 5-16.
6. Install the fuel cap.
7. Start the engine and let it run for a few minutes. If
the engine stalls, the fuel system may need to be
primed. While draining the water from the fuel filter,
air may enter the fuel system. If air has entered
the fuel system the fuel system will need to
be primed.
If the WATER IN FUEL message comes on again after
driving a short distance or the engine runs rough or
stalls, a large amount of water has probably been
pumped into the fuel tank. The fuel tank should be
purged.
Fuel Priming
In order for the fuel system to work properly, the fuel
lines must be full of fuel and contain no air. If air
gets into the fuel lines, it will be necessary to prime the
fuel lines, to eliminate air before operating the vehicle.
