Removal
NOTICE: To release the fuel pressure in the high-pressure fuel tube, wrap the high-pressure fuel tube flare nuts with a shop towel to absorb any residual fuel pressure during the loosening of the flare nuts.
Disconnect the high-pressure fuel tube flare nuts, then remove and discard the high-pressure fuel tube.NOTICE: Pull out the fuel rails in the direction of the fuel injector axis or damage may occur to the fuel injectors.
NOTICE: Use minimal force to remove the fuel injectors that remained in the cylinder head with the Fuel Injector Remover tool or damage to the fuel injector assembly may occur. Wiggling the injector by hand to break it loose may allow the injector to be removed by hand.
NOTE: Commercially available OTC 5028 8-1/2" long slide hammer may be substituted for 307-005 where there are clearance concerns.
Using the special tools, remove any of the fuel injectors that remained in the cylinder head.NOTICE: Do not use compressed air to clean the tip of the fuel injector.
NOTICE: Do not use a brush to clean the tip of the fuel injector.
NOTICE: Make sure to thoroughly clean any residual fuel or foreign material from the cylinder head, block and the general surrounding area of the fuel rails and injectors.
NOTE: Note the correct orientation of the fuel injector support rings, to insure the correct installation of the new fuel injector support rings.
NOTICE: Use care when removing the lower Teflon® seals, not to scratch, nick or gouge the fuel injector.
NOTICE: Do not attempt to cut the lower Teflon® seal without first pulling it away from the fuel injector or damage to the injector may occur.
Installation
NOTICE: Do not lubricate the new lower Teflon® fuel injector seals.
NOTICE: Once the Teflon® seal is installed on the Teflon® Seal Guide, it should immediately be installed onto the fuel injector to avoid excessive expansion of the Teflon® seal.
NOTE: Make sure that new lower fuel injector Teflon® seals are installed.
Install the new Teflon® seals onto the Teflon® Seal Guide, using the Pusher Tool, slide the Teflon® seals along the Teflon® Seal Guide.NOTE: Make sure the Teflon® seal is fully seated in the groove on the fuel injector before sizing the Teflon® seal.
NOTE: The beveled opening of the Teflon® seal sizer tool goes away from the seal.
NOTE: Do not use the injector without re-forming the Teflon seal after replacing.
NOTE: Make sure that new fuel injector support rings, new fuel injector O-ring seals and new fuel injector clips are installed.
NOTICE: The new the fuel injector support rings must be installed in the correct orientation with the wide surface area facing up against the fuel injector O-ring seals. Improperly installed support rings may cause the fuel system to leak.
Install the new the fuel injector support rings.NOTICE: Do not re-use a fuel injector if it is dropped.
Install the fuel injectors to the fuel rail.NOTE: Do not lubricate the new lower Teflon® fuel injector seals.
Install the fuel rail, push down on the fuel rail above the injectors, then tighten the fuel rail bolts in the following 2 stages, in the sequence shown.NOTICE: In stage 3, if the torque required to tighten any flare nut on the new high-pressure fuel tube reaches or exceeds 55 lb.ft (75 Nm), then that high pressure fuel tube must be discarded and replaced with another new high-pressure fuel tube.
NOTE: Make sure that a new fuel rail to fuel rail high-pressure fuel tube is installed.
NOTE: Calculate the correct torque wrench setting for the following torque using the Torque Wrench Adapter Formulas.
Install the fuel rail to fuel rail high-pressure fuel tube and tighten the flare nuts finger tight, then tighten the flare nuts in the following 3 stages.Check
NOTE: Wheel-to-hub optimization is important. Clearance between the wheel and hub can be used to offset or neutralize the Road Force® or run-out of the wheel and tire assembly. For every 0.001 inch of wheel-to-hub clearance, the Road Force® can be affected between 1 and 3 pounds depending on the tire stiffness.
NOTE: The example below illustrates how the clearance between the wheel and the hub can be used to offset the high spot of radial run-out or Road Force®. Following the procedure will make sure of the best optimization.
Position the wheel and tire assembly on the vehicle so that the high spot location of radial run-out or Road Force® is at the 6 o'clock position and
