there four bolt for my fuel rail.. lol.. so the injector is not like it clip in or turn it in with a screw .. or something ?unclip the injector clip(s)
remove the two bolts on the fuel rail and pull it out :thumbs up
well i will pull it out in my garage so no need to worry.. but o ring ?? what does it look like and where to get a new oneno, soon as you take off the fuel rail and the clips they just pull right out. and you need to be careful of the o-rings, if they sit in the sun too long they will dry out easily so as soon as you get it out keep them out of sunlight. had a buddy of mine not know that and when he put them back after cleaning out the filters, it didnt leak for the time we checked it but then his ish caught on fire right before he got home. that sucks.
