Diesel Fuel-Water Separator
A diesel fuel-water separator separates the water nor-
mally found in diesel fuel. A manual hand prime pump is
located on the filter head for re-priming the fuel system.
The fuel-water separator is located on the driver side
cowl in the engine compartment. Refer to “2.8L Turbo
Diesel Engine Compartment” in Section 7 for location.
NOTE: If the “Water-In-Fuel Warning Light” (located in
the instrument cluster) comes on, this indicates that
water has collected in the fuel filter and should be
drained immediately. See your authorized dealer for
service.
Should your vehicle run out of fuel, the fuel system must
be re-primed in order to start the engine. Factors such as
temperature, which affects the viscosity of the fuel, how
long the vehicle has been sitting and other factors will
influence how quickly the engine starts.
Re-Priming the Diesel Fuel System
The following procedure must be followed after com-
pletely running out of fuel.
1. Add a minimum of 2 gallons (7.57L) of diesel fuel to
the fuel tank.
2. Open the hood.
