I have a leaky injector on top by the fuel rail[I hope], is my first jeep so any tips would be nice.It looks pretty st. forward but I,ve been done that road before.I only thing that concerns me is how to disconnect the fuel line from the rail.Is a plastic push or pull connecter which I don,t have a tool for.Any pics would be nice too Thanks

push metal line in, squeeze plastic tabs, pull fuel line... its pretty easy
if its a auto you have to remove the kick down cable from the bracket.

Yes is auto,do I have to put anything on the o rings vaseline ,oil etc. Other dumb ? where do the o rings go, on the injector or on the fuel rail,I,m sure I wiill see once I take it apart but I,m just trying to get my poop in a group so I can get it done as is getting cold out this weekend.

1 o ring on top of injector and one on bottom. Vaseline or neosporin works.
also brake lube called sylglide or something like that lol..

OK hopefully one last ?.I didn,t know there was two per cylinder.So I take it you have to pull the injector out and there is one there at the bottom that goes into the intake,if so does the injector just pull out.Sorry for all the questions but is my first newer truck,all my stuff is basic carb stuff.I did look on the internet for some time but found nothing on this question

1 injector per cyl 2 o rings per injector. you pull the fuel rail and pull up on it.
some times the orings will stick in the holes thats just an fyi. here is a pic of what it will look like

remember to bleed off the fuel pressure and disconnect the battery before pulling the rail/injectors.

To bleed off the pressure there is a small cap couple inches passed the fuel pressure regulator (the round thing in front of the fuel rail) Make sure the motor is cold and unscrew the cap it will look like a bycicle or tire air valve. place a rag under the nipple and use a screwdriver and push in the pin. this will relieve the fuel pressure so you dont make a mess when removing the other lines.

Another way you can bleed the pressure is by pulling the fuse for the fuel pump and turn the motor over for a few secs.
