Question about 1989 Ford Crown Victoria
You should get a mechanic's manual for this, but I will walk you through the steps:
1.bleed the fuel rail of pressure at the valve on rail
2.undo all the harness connectors from each injector and label their position
3.unbolt the fuel rail from the block/manifold
4. wiggle and pull the rail unit from each side carefully as not to damage the injectors
5.one at a time remove clip that retains injector to rail and separate from rail
6.remove old o-rings (a dental tool or similar is helpful, but do not scratch or score injector body)
7.install o-rings with auto trans fluid as a lubricant carefully into rail and seat fully before attaching clip
8.clean and lubricate each port in intake manifold before attempting to install each rail as a unit
9. use care and patience as you wiggle the unit into a fully seated position checking all four injector positions as you go
10.torque bolts to specifications,reinstall harness
11. when done, turn on key breifly to allow pump to pressurize system and bleed air from rail, repeat
12.start motor and allow to run while checking for leaks
any other questions-just reply, should be around all day...MK

You unbolt the entire fuel rail from the intake manifold and pull it up gently. You can leave the rail connected to the fuel supply hose. You may need to remove the connectors as well to get it up high enough to change the o-rings. use a little oil or grease on the orings to slip them back in the same way you pulled it out. If you have more questions, let us know.
