Important: When servicing the fuel rail assembly, precautions must be taken to prevent dirt and other contaminants from entering the fuel passages. It is recommended that the fittings be capped, and the holes be plugged during servicing.
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:
• Use care when servicing the fuel system components, especially
the fuel injector electrical connectors, the fuel injector tips, and
the injector O-rings. Plug the inlet and the outlet ports of the fuel rail
in order to prevent contamination. • Do not use compressed air to clean the fuel rail assembly as this
may damage the fuel rail components. • Do not immerse the fuel rail assembly in a solvent bath in order
to prevent damage to the fuel rail assembly.
Tighten
Torque the fuel rail hold-down bolts to 10 N·m (7 lb ft).
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.
