To install:


NOTE
When replacing the fuel injector O-rings install the brown O-ring in the lower position. The lower O-ring uses a nylon collar to properly position it on the injector. Be sure to install the O-ring backup or the sealing O-ring may move when the injector is installed to the fuel rail. If the sealing ring is not seated properly, a vacuum leak is possible thus causing driveability complaints.

  1. Install or connect the following:

    Upper O-ring to the fuel injector
     
    Lower O-ring backup to the injector
     
    Lower O-ring to the injector
     
    Fuel injector to the fuel rail
     
    Fuel rail with the retaining clips
     
    Upper intake manifold
     
    Negative battery cable

  3. Prime the fuel system as follows:
    1. Turn the ignition switch ON for two seconds.
    2.  
    3. Turn the ignition switch OFF for 10 seconds.
    4.
