Fuel leak from top of injector,

[Loofee95SE]

'Well I drove my car This moring after it 's been sitting on my driveway for a few COLD days. I start the car, warm it up, drove and boost fine ..then when I about a block from home...sniff ** sniff** I smell raw fuel the Ooo so familia fuel smell . but ! usually not from this car!! my Rx7 smell like fuel not my S13....damn . so i pulled in to the drive way..pop the hood...and there it was...puddle of fuel leaking from #4 injector from the top where it connected to the rail.so my 1st guess will be, that my o-ring crap out on me. Now...it look like a pretty easy job to me...but to those who have done this before...is there any trick that I need to know about before I start wrenching??? and does anybody have the part # for O-ring from Nissan?? Thanks...C

It's pretty straight forward. -Remove the fuel pump fuse and start the car-Let it run till it dies-Crank for another 15 sec to clear fuel lines-Lable and unhook the assorted wiring-Remove the idle control crap attached to the side of the mani-Remove the clamps and fuel lines from the rail-Remove the 2 bolts attaching the fuel rail to the mani-Remove the fuel rail-Remove ALL injectors and replace ALL the O-rings

Installation is reverse of removal.

You might want to get a new gasket for the idle crap in case the gasket self destructs removing it

For the O rings I used 4G63 ones, but I had to stack 2 on each injector (MSD 72#'s). Hope that helps.

why 2 on each injectors?? well i guess that the O-ring from FC wil work as well...hmm....I just still don't understand why all the sudden it crap out on me....o well. C

There skinnier then the original O rings from nissan so I just stack if that makes sense.

Where the hello did you get a gaket for that? I didn't think the pulsar one was the same. Maybe I'm wrong? I had to use RTV. I hate doing that...
