Default LS3 Holley Hi Ram Injector O-Ring size?

So I have ID2000s that were in my stock LS3 manifold. Just swapped over to a Holley Hi Rise and the O-Ring into the manifold is too big. The injector base fits into the hole, but the O-ring is too large. I don't get it, should fit. Has anyone had this issue? I understand getting new O-rings should resolve it but wondering what I am missing. Haven't tried the top end into the rail so not sure if that one is mismatched as well.

Yes sorry you should've pm me I would have walked you through. Swap out the top o ring on the injector with the bottom, I had to do it with my id1000's
