Removal
1) Remove nameplate located above rocker lever covers. Remove
fuel injector drain line-to-fuel injector banjo bolt and seal washer
from each fuel injector. Plug all fuel openings.
2) Remove fuel injector drain line assembly retaining clamp
at rear of intake manifold. Remove fuel injector drain line bolt with
seal washers at filter mounting head. See Fig. 3. Remove fuel injector
drain line assembly.
Installation
To install, reverse removal procedure using NEW seal washers.
Tighten bolts to specification. See TORQUE SPECIFICATIONS.
FUEL HEATER
Removal & Installation
Fuel heater is located in FUEL FILTER/WATER SEPARATOR &
WATER-IN-FUEL SENSOR. See FUEL FILTER/WATER SEPARATOR & WATER-IN-FUEL
SENSOR.
FUEL INJECTOR
Removal
1) Disconnect negative battery cables. Each fuel injector is
connected to each high-pressure fuel line with a steel connector line.
Steel connector is positioned into cylinder head and sealed with "O"
ring. See Fig. 8. If removing injector at cylinder No. 1 or No. 2,
remove intake manifold air heater assembly. If removing injector at
cylinder No. 5, remove engine lifting bracket. Ensure area around fuel
injector and high-pressure fuel line is clean. Disconnect high-
pressure fuel line at fuel injector. DO NOT bend any high-pressure
fuel line to gain access to fuel injector. It may be necessary to
remove high-pressure fuel lines from fuel injection pump for access to
fuel injector.
2) If removing high-pressure fuel lines from fuel injection
pump, mark high-pressure fuel line location for installation
reference. Remove valve cover. Thread Fuel Injector Connector Tube
Remover (8324) onto end of injector connector tube. Remove and discard\
old "O" ring from injector connector tube.
3) Remove fuel injector hold down clamp bolt at front end of
clamp. DO NOT loosen or remove shouldered bolt at rear of clamp.
Remove injector clamp by sliding it from shoulders on rear clamp bolt.
Thread rod from fuel injector remover into top of fuel injector.
Tighten nut to remove fuel injector from cylinder head. Remove and
discard "O" ring and copper sealing washer.

Installation
1) Clean fuel injector bore on cylinder head with wire brush.

1) Fuel filter/fuel pressure regulator is mounted in rubber
grommet on top of fuel pump module. See Figs. 27-30. Fuel pump module
is located on top of fuel tank.
2) Manufacturer recommends removing fuel tank for access to
fuel filter/fuel pressure regulator. See FUEL TANK. Ensure area around
fuel filter/fuel pressure regulator and fuel pump module is clean.
CAUTION: When removing fuel filter/fuel pressure regulator from fuel
tank, DO NOT pull fuel filter/fuel pressure regulator more
than 3.0" (76 mm) from fuel tank or plastic fuel line
attached to fuel filter/fuel pressure regulator may be
damaged.
3) Using twisting motion, pull fuel filter/fuel pressure
regulator from rubber grommet on fuel pump module. Ensure fuel
filter/fuel pressure regulator is not pulled more than 3.0" (76 mm)
from fuel tank or plastic fuel line attached to fuel filter/fuel
pressure regulator may be damaged.
4) Carefully cut plastic fuel line-to-fuel filter/fuel
pressure regulator retaining clamp. Use care not to damage plastic
fuel line. Remove retaining clamp. Remove plastic fuel line from fuel
filter/fuel pressure regulator.
Installation
1) Install plastic fuel line with NEW retaining clamp on fuel
filter/fuel pressure regulator. Rotate fuel filter/fuel pressure
regulator in plastic fuel line until fuel line fitting on side fuel
filter/fuel pressure regulator points proper direction. See
POSITIONING FUEL FILTER/FUEL PRESSURE REGULATOR table.

CAUTION: Ensure Crimping Pliers (C-4124) are used to crimp retaining
clamp for plastic fuel line. DO NOT use conventional side
cutters to crimp retaining clamp.
2) Using Crimping Pliers (C-4124), crimp retaining clamp for\
plastic fuel line. Ensure plastic fuel line is securely attached on
fuel filter/fuel pressure regulator.
3) To install remaining components, reverse removal
procedure. Ensure fuel filter/pressure regulator is installed in
rubber grommet on fuel pump module so fuel line fitting on side fuel
filter/fuel pressure regulator points toward proper direction before
installing fuel tank. See POSITIONING FUEL FILTER/FUEL PRESSURE
REGULATOR table. Reinstall fuel tank using proper procedure.

Removal & Installation
Fuel pressure regulator is incorporated with the fuel filter.
For servicing for fuel filter/fuel pressure regulator, see FUEL
FILTER/FUEL PRESSURE REGULATOR.
FUEL PUMP
Removal & Installation
Fuel pump is incorporated into the fuel pump module. See FUEL
PUMP MODULE.
FUEL PUMP INLET STRAINER
Removal & Installation
1) Fuel pump inlet strainer is mounted on fuel pump module.
See Fig. 31 . Remove fuel pump module. See FUEL PUMP MODULE.
2) Spread locking tabs on bottom of fuel pump module and
remove fuel pump inlet strainer from fuel pump module. See Fig. 31.
Remove "O" ring from end of fuel pump module if "O" ring was not
removed with fuel pump inlet strainer.
3) To install, reverse removal procedure. Ensure "O" ring is
properly seated when installing fuel pump inlet strainer. Reinstall
fuel pump module using proper procedure.
FUEL PUMP MODULE
Removal (Dakota)
1) Fuel pump module is located on top of fuel tank. See
Fig. 27 . Fuel tank must be removed for servicing of fuel pump module.
Remove fuel tank. See FUEL TANK.
2) Ensure area around fuel pump module is clean. Using Fuel
Pump Module Lock Nut Spanner Wrench (6856), remove fuel pump module
lock nut. See Fig. 32. Remove fuel pump module with rubber gasket from
fuel tank.
CAUTION: When fuel pump module is removed from fuel tank, rubber
gasket must be replaced. DO NOT reuse rubber gasket.
Installation
1) Ensure sealing area on fuel tank is clean. Using NEW
rubber gasket, install fuel pump module on fuel tank. DO NOT reuse
rubber gasket. Ensure rubber gasket remains in place.
NOTE: Fuel pump module must be properly positioned in fuel tank to

module is at 7 o'clock position and aligns with reference mark on fuel
tank. See Fig. 33. Install and hand tighten fuel pump module lock nut.
3) Note location of fuel pressure regulator on fuel pump
module. See Fig. 27. Ensure fuel filter/pressure regulator is
positioned on fuel pump module so fuel line fitting on side fuel
filter/fuel pressure regulator points toward driver's side of vehicle.
4) Hold fuel pump module in place while tightening fuel pump
module lock nut to specification. See TORQUE SPECIFICATIONS. Reinstall
fuel tank using proper procedure.

Fig. 28. Fuel tank must be removed for servicing of fuel pump module.
