RC injector install question

[GSRCRXsi]

well i was looking at my RC injectors and something didnt seem right. the part that attaches to the fuel rail seems too short. the helms shows that the injector extends into the fuel rail a bit before pressing against the cushion ring. the rc seems to be too short though as the o-ring is right up against the cushion ring. has anyone ever come to this problem? how did you fix it?

picture to show what im talking about.

Maybe cut the cushion in half? I had all sorts of weird sizing issues when I put in my injectors. You'll probably also have to remove that plastic spacer for the fuel rail, to get it sit closer to the injector. My 550's I had, I had to cut up my rings to get it to work right, the 440's weren't such a pain for some reason.
