I was putting my fuel rail back on but one of the o-rings on the injectors broke so I have to get new ones. I know the lower o-ring on the injectors sits inside the lim snugly. When you put your o-rings on the top of the injectors is the fuel rail rail just supposed to sit on top of them or do they have to fit snugly like the bottom part of the injectors do in the lim?

They should be somewhat snug, but not really tight. You should always put a light coating of oil around the o-rings with your finger before installing them in the rail or the manifold. That will make them go in and come out easier so you don't accidentally tear one.
