Installation Procedure
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 blue), be sure to install the blue O-ring in the upper position and the black O-ring in the lower position on the fuel injector. The O-rings are the same size but are made of different materials.
Important:
• Be sure to use the correct part number when ordering replacement
fuel injectors. • The fuel injector O-rings should always be replaced whenever the
fuel injectors are serviced. Be sure to install the correct O-ring for
the fuel injector. If the O-ring is not seated properly, a vacuum leak
is possible and driveability complaints may occur.

- Install the new upper and lower injector O-rings on the fuel injector.
- Install the fuel injector on to the fuel rail.
