Refer to the maintenance schedules for the recom-
mended fuel filter replacement intervals.
For draining of water from canister, refer to Fuel
Filter/Water Separator Removal/Installation section.
A Water-In-Fuel (WIF) sensor is part of the fuel fil-
ter cap. Refer to Water-In-Fuel Sensor Description/
Operation.
The fuel heater is installed into the filter/separator
housing above the fuel filter. Refer to Fuel Heater
Description/Operation.
FUEL LINES
DESCRIPTION
DESCRIPTION
All fuel lines up to the fuel injection pump are con-
sidered low-pressure. This includes the fuel lines
from: the fuel tank to the fuel transfer pump, and
the fuel transfer pump to the fuel injection pump.
The fuel return lines and the fuel drain lines are also
considered low-pressure lines. High-pressure lines
are used between the fuel injection pump and the
fuel injectors. Also refer to High-Pressure Fuel Lines
Description/Operation.
DESCRIPTION - HIGH PRESSURE FUEL LINES
The high-pressure fuel lines are the 4 lines located
between the fuel injection pump and the fuel injec-
torsctor tubes. All other fuel lines are considered low-
pressure lines.
OPERATION - HIGH PRESSURE FUEL LINES
CAUTION: The high-pressure fuel lines cannot con-
tact each other or other components. Do not
attempt to weld high-pressure fuel lines or to repair
lines that are damaged. If lines are ever kinked or
bent, they must be replaced. Use only the recom-
mended lines when replacement of high-pressure
fuel line is necessary.
High-pressure fuel lines deliver fuel under
extremely high pressure from the injection pump to
the fuel injectors. The lines expand and contract from
the high-pressure fuel pulses generated during the
injection process. All high-pressure fuel lines are of
the same length and inside diameter. Correct high-
pressure fuel line usage and installation is critical to
smooth engine operation.
WARNING: USE EXTREME CAUTION WHEN
INSPECTING FOR HIGH-PRESSURE FUEL LEAKS.
INSPECT FOR HIGH-PRESSURE FUEL LEAKS WITH
A SHEET OF CARDBOARD. HIGH FUEL INJECTIONPRESSURE CAN CAUSE PERSONAL INJURY IF
CONTACT IS MADE WITH THE SKIN.
DIAGNOSIS AND TESTING - HIGH PRESSURE
FUEL LINES
High-pressure fuel line leaks can cause starting
problems and poor engine performance.
WARNING: DUE TO EXTREME FUEL PRESSURES,
USE EXTREME CAUTION WHEN INSPECTING FOR
HIGH-PRESSURE FUEL LEAKS. DO NOT GET YOUR
HAND NEAR A SUSPECTED LEAK. INSPECT FOR
HIGH-PRESSURE FUEL LEAKS WITH A SHEET OF
CARDBOARD. HIGH FUEL INJECTION PRESSURE
CAN CAUSE PERSONAL INJURY IF CONTACT IS
MADE WITH THE SKIN.
Start the engine. Move the cardboard over the
high-pressure fuel lines and check for fuel spray onto
the cardboard (Fig. 4). If a high-pressure line connec-
tion is leaking, bleed the system and tighten the con-
nection. Refer to the Air Bleed Procedure in this
group for procedures. Replace damaged, restricted or
leaking high-pressure fuel lines with the correct
replacement line.

CAUTION: The high-pressure fuel lines cannot con-
tact each other or other components. Do not
attempt to weld high-pressure fuel lines or to repair
lines that are damaged. Only use the recommended
lines when replacement of high-pressure fuel line is
necessary.
FUEL TRANSFER PUMP
DESCRIPTION
The fuel transfer pump (fuel lift pump) is located
under the vehicle in front of the rear axle assembly
(Fig. 5). The 12±volt electric vane-type pump is oper-
ated and controlled by the Engine Control Module
(ECM).
OPERATION
The purpose of the fuel transfer pump is to supply
(transfer) a low-pressure fuel source:fromthe fuel
tank,throughthe fuel filter/water separator andto
the fuel injection pump. Here, the low-pressure is
raised to a high-pressure by the fuel injection pump
for operation of the high-pressure fuel injectors.
The fuel transfer pump is controlled by the Engine
Control Module(ECM). The ECM turns the fuel
transfer pump on for 30 seconds when the ignition
ket is turned ªONº.
With the ignition ªONº and fuel tranfer pump run-
ning, the low-pressure fuel pressure should be 13-17
psi.
FUEL INJECTION PUMP
DESCRIPTION
A radial-piston pump is used as the high pressure
pump for fuel pressure generation (Fig. 6).
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL)
(3) Remove air cleaner housing assembly.
(4) Remove power steering belt (Refer to 7 -

POWER TRANSFER UNIT
DESCRIPTION
The Power Transfer Unit (P.T.U.) is attached to a
modified automatic transaxle case where the right
half shaft extension housing would normally be
located.
The Power Transfer Unit is sealed from the trans-
axle and has its own oil sump. The Unit uses MopartSAE 80W-90 Gear and Axle Lubricant (MS-9020) and
holds 1.15 liters (1.22 quarts).
Service of the Power Transfer Unit is limited to:
²Fluid Change
²Seals
²Gaskets
²One ball bearing
²Output flange
If the ring gear and pinion, any tapered roller
bearings, case, covers, or pinion carrier fail the entire
unit must be replaced.
