fuel injector/fuel rail question

I'm in the middle of changing out the manifold in my 99 xj, and upon removing the fuel rail/injectors from the top of the intake manifold 2 of the injectors came apart from the fuel rail. I've been spending way too much time trying to get those injectors back into the hole on the fuel rail where they belong but no luck. Those little o rings don't seem to want to compress enough(under human strength anyway)to pop back into place. Does anyone know what I'm talkin about and what is the trick? Is there a compression tool of some sort used to seat the injector properly? Much appreciation to the one or ones who can help.

I had one injector pop out and it is a pain to get it back in but i just pushed it in and i think i tried rotating it while pushing it in. It took me a few times to get it back in but it finally went back in.

Alot of relief and a little embarassment.., immediately after my 1st post I tryed it again and this time for the hell of it I used a small amount of grease on the o rings and aroung the opening on the rail, and wouldn't ya know it after all night both injectors popped right in no prob! A small amount of grease...
Thanks for the input man.
