WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
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.

An 8-digit identification number is located on the fuel rail assembly. Refer to this model identification number if servicing or part replacement is required. Fuel injector "O" rings should always be replaced whenever the fuel injectors are serviced.
