Installation Procedure
WARNING:
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.
NOTE:
- Be sure to use the correct part number when ordering replacement fuel injectors.
- The fuel injector O-ring seal should always be replaced whenever the fuel injectors are serviced. Be sure to install the correct O-ring seal for the fuel injector. If the O-ring seal is not seated properly, a vacuum leak is possible and driveability complaints may occur.
- Lubricate the NEW O-rings seals with clean engine oil.
- Install the NEW upper (2) and lower (4) injector O-rings seal onto the fuel injector.
- Install the fuel injector (3) into the fuel rail.
- Install the fuel injector fuel rail clip (1).
- Install the fuel rail. Refer to Fuel Injection Fuel Rail Assembly Replacement .
