DSM injector help

[yourmomsrps13]

ok so im rebuilding my motor and decided to use my moddified manifold and these 450 DSM injectors but i just ran into the problem of the injector wont seat correctly, i switched O rings and it still wont butt up against the seal

Mine did the same thing. But the way the plastic meets the fuel rail still makes it so that it presses the end of the injector down into manifold-side o-ring. ****'s all good, I checked for leaks and there were none.
