I am installing the RC 550 injectors and it appears that I do not use the two cushion o rings on the bottom injector. Is this correct? The injectors came with a black and green o-ring on the top side. The black was the highest followed by a green one. The green ones were torn a bit so I pulled the o-ring off the stock injectors and put those on the RC 550s.
Now to my issue with bottom cushions. On the stock injector is one the fits into the intake and another that sorta of goes around the injector. When I try both with the RC 550 I was having issues getting the fuel rail pushed down far enough to engage the nuts. Maybe I was tired and need to try again in better light but maybe I use only the thicker of the two on the bottom?
