1. What is the best way to take off the fuel rail? I've seen people pull it off with the injectors still in it and just bungee-cord it off to the side. Do I have to depressurize the fuel system first?
2. Do I have to do anything when reinstalling the fuel rail/fuel injectors? Change any o-rings, etc?
3. What else am I missing?
Thanks to anyone who can help. I'm 90% of the way there - just want to make sure I can do this without breaking anything else in the process. I'm off to the dealer to pick up the gaskets today and I'll see if they have the correct sealant for the corners.

This is a pretty straight forward deal. The fuel rails are held in place by 4 (or 6, I can't remember) screws. They screw directly into the intake manifold. Just remove those screws, and lift the rails up. It may take some light rocking or back and forth, but it should come right up. I removed my fuel line going to the rails, but I don't believe its required. If you don't remove it, the rail assy. will just flip over toward the passenger side. You can replace the o-rings, but it's not required. They can be purchased from rockauto or you can check with your local store. The problem with replacing the o-rings is that you need a dental pick to pry them out.
When you are done doing what you need to do, just push the injectors back into their hole. One caveat here is to take a shop vac and clean around every injector BEFORE you pull them out. Mine had tons of small particulate matter like dead bugs around them.
Good luck.
