INSTALLATION
(1) Inspect fuel injector:
(a) Look for burrs on injector inlet.
(b) Check nozzle holes for hole erosion or plugging.
(c) Inspect end of nozzle for burrs or rough
machine marks.
(d) Look for cracks at nozzle end.
(e) If any of these conditions occur, replace injector.
(2) Thoroughly clean fuel injector cylinder head
bore. Blow out bore hole with compressed air.
(3) The bottom of fuel injector is sealed to cylinder
head bore with a copper sealing washer (shim) of a certain thickness (Fig. 20). A new shim with correct
thickness must always be re-installed after removing
injector. Measure thickness of injector shim (Fig. 21).
Shim Thickness: 1.5 mm (.060”)
(4) Install new shim (washer) to bottom of injector.
Apply light coating of clean engine oil to washer. This
will keep washer in place during installation.
(5) Install new o-ring to fuel injector. Apply small
amount of clean engine oil to o-ring.
(6) Install injector into cylinder head with male
connector port facing the intake manifold. Push down
on fuel injector mounting flange to engage o-ring and
seat injector.
(7) Tightening Sequence:
(a) Install fuel injector holdown clamp (mounting
flange) bolts. Do a preliminary tightening
of these bolts to 5 N·m (44 in. lbs.) torque.
This preliminary tightening insures the fuel
injector is seated and centered.
(b) After tightening, relieve bolt torque, but
leave both bolts threaded in place.
(c) Install high-pressure connector and retaining
nut. Do a preliminary tightening to 15 N·m (11 ft.
lbs.) torque.
(d) Alternately tighten injector holdown bolts to
10 N·m (89 in. lbs.) torque.
(e) Do a final tightening of the high-pressure
connector and retaining nut. Tighten to 50 N·m (37
ft. lbs.) torque.
(8) Connect injector solenoid wires and nuts to top
of injectors (Fig. 18). Tighten connector nuts to 1.25
N·m (11 in. lbs.) torque. Be very careful not to
overtighten these nuts as damage to fuel injector
will occur.
(9) Install exhaust rocker arm assembly. Refer to
Engine.
(10) Set exhaust valve lash. Refer to Engine.
(11) Install high pressure fuel line. Refer to Torque
Specifications. Be sure to use a secondary
back-up wrench on the connector nut (fitting)
while torquing fuel line fitting. Refer to Fuel Line
Installation for additional information.
(12) Install valve cover. Refer to Engine.
(13) Install breather assembly.
(14) Connect negative battery cables to both batteries.

This is for an 04, but it should be the same...
