Here is what I was able to find for you. NOTE: Before removing the fuel rail, make sure it is clean to prevent dirt contamination from entering the fuel system.

Properly relieve the fuel system pressure and disconnect the negative battery cable.
Remove the air intake duct, as necessary for access.
Tag and disengage the fuel injector electrical connectors.
Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
Loosen and remove the fuel rail retaining bolts.
If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
Carefully lift the fuel rail assembly and fuel injectors from the intake.
Carefully release and separate the fuel injectors from the rail assembly.
Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.

Finally, place a light film of motor oil on the o-ring before reintalling it.

Reverse the process to replace.

Let me know if you have any questions.
