I was wondering if when you guys seat your injectors do you or should you see any of the yellow flange (plastic piece above the rubber o-ring)?? I have all mine seated but I still see a tiny bit of the yellow on the front passenger side injectors and they don't want to go in any further, I don't know if they are seated completely or if the o rings are in far enough to seal or not. Just wanted to get a few opinions from some of you guys.

 

turn the key on and see if they leak, thats the only way your gonna know

 

No I don't on mine.....when I put mine in I put them in the rails first, got the rail bolts started then went from injector to injector and pushed each one down...you should feel a pop when the pop down in place. Then I tightened the rail bolts down tight....haven't had a bit of problem. Make sure the o-rings are lubed good...I used motor oil.
