Tools Required

Notice: 

1. Relieve fuel system pressure. Refer to Fuel Pressure Relief .
2. Disconnect the IAT sensor electrical connector (1).



3. Disconnect the MAF sensor electrical connector (1).
4. Remove the air cleaner intake duct (3).
5. Clean the fuel rail assembly and fuel pipe connections.



6. Remove the quick-connect fittings (2, 4) at the fuel rail. Refer to Metal Collar Quick Connect Fitting Service .



7. Remove the fuel pressure regulator vacuum hose.



8. Remove the PCV air tube.



9. Remove the fuel rail end-point bracket retainer nut.



10. Remove the fuel injector electrical connectors from the fuel injectors.
11. Lay the harness aside.



12. Remove the fuel rail attaching bolts (2).
13. Raise the fuel injectors from the intake manifold with J 43013 .

Important: Store the fuel rail assembly in a clean secure location away from heat sources.

14. Lift the fuel rail and remove the fuel rail.
15. Remove the injector lower O-ring seal from the spray tip end of each injector.
16. Discard the O-ring seals.

Caution: In order to reduce the risk of fire and personal injury that may result from a fuel leak, always install the fuel injector O-rings in the proper position. If the upper and lower O-rings are different colors (black and brown), be sure to install the black O-ring in the upper position and the brown O-ring in the lower position on the fuel injector. The O-rings are the same size but are made of different materials.

Notice: 

1. Lubricate the new lower injector O-ring seals with clean engine oil.
2. Install the new O-ring seals on the spray tip end of each injector.
3. Install the fuel rail assembly on to the intake manifold until the fuel injectors are fully seated.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
