DESCRIPTION AND OPERATION
FUEL DELIVERY SYSTEM
The front wheel drive van uses a plastic fuel tank
located on the left side of the vehicle.
The Fuel Delivery System consists of: the electric
fuel pump module, fuel filter, tubes/lines/hoses, fuel
rail, and fuel injectors.
The in-tank fuel pump module contains the fuel
pump and pressure regulator. The pump is serviced
as part of the fuel pump module. Refer to Fuel Pump
Module.
The fuel filter is a replaceable in-line filter. The fil-
ter attaches to a bracket mounted on top of the fuel
tank. Refer to the Maintenance Schedules in the
Introduction section of this manual for recommended
fuel filter replacement intervals.
A returnless fuel system is used on all vehicles.
Fuel is returned through the fuel pump module and
back to the fuel tank. A separate fuel return line
from the tank to the engine is no longer used.
FUEL PUMP MODULE
The fuel pump module is installed in the top of the
fuel tank (Fig. 1). The fuel pump module contains the
following:
²Electric fuel pump
²Fuel pump reservoir
²Inlet strainer²Fuel pressure regulator
²Fuel gauge sending unit
²Fuel supply line connection
The inlet strainer, fuel pressure regulator
and fuel level sensor are the only serviceable
items. If the fuel pump or electrical wiring har-
ness requires service, replace the fuel pump
module.
ELECTRIC FUEL PUMP
The electric fuel pump is located in and is part of
the fuel pump module. It is a positive displacement,
gerotor type, immersible pump with a permanent
magnet electric motor. The pump draws fuel through
a strainer and pushes it through the motor to the
outlet. The pump contains one check valve. The

DESCRIPTION AND OPERATION
INTRODUCTION
This Fuel Delivery section will cover components
not controlled by the PCM. For components con-
trolled by the PCM, refer to the Fuel Injection Sys-
temÐ2.5L Diesel Engine section of this group.
The fuel heater relay, fuel heater and fuel gauge
are not operated by the PCM. These components are
controlled by the ignition (key) switch. All other fuel
system electrical components necessary to operate
the engine are controlled or regulated by the PCM.
FUEL SYSTEM PRESSURE WARNING
WARNING: HIGH±PRESSURE FUEL LINES DELIVER
DIESEL FUEL UNDER EXTREME PRESSURE FROM
THE INJECTION PUMP TO THE FUEL INJECTORS.
THIS MAY BE AS HIGH AS 45,000 KPA (6526 PSI).
USE EXTREME CAUTION WHEN INSPECTING FORHIGH±PRESSURE FUEL LEAKS. INSPECT FOR
HIGH±PRESSURE FUEL LEAKS WITH A SHEET OF
CARDBOARD (Fig. 1). HIGH FUEL INJECTION
PRESSURE CAN CAUSE PERSONAL INJURY IF
CONTACT IS MADE WITH THE SKIN.
FUEL TANK
The fuel tank and tank mounting used with the
diesel powered engine is the same as used with gas-
oline powered models, although the fuel tank module
is different.
The fuel tank contains the fuel tank module and
two rollover valves. Two fuel lines are routed to the
fuel tank module. One line is used for fuel supply to
the fuel filter/water separator. The other is used to
return excess fuel back to the fuel tank.
The fuel tank module contains the fuel gauge elec-
trical sending unit.An electrical fuel pump is not
used with the diesel engine.

Be sure the lines are not contacting each
other or any other component.
(5) Tighten the clamp bracket bolts to 24 N´m (18
ft. lbs.) torque.
(6) Bleed air from the fuel system. Refer to the Air
Bleed Procedure section of this group.
