1G Is this right with these injectors?

So these are 650 injectors. I have new rubber pieces that seat on the bottom of the injector and go into the block. I also have the blue orings that go on top of the injectors. The other black piece that goes on top of the injector I reused from the old injector. They aren't the same size as you can see in the pic. Is this setup correct?

There's a little black plastic piece on the bottom of the injectors. I've been looking at other pictures and I don't see them on there. Do I need the little black piece on the injectors?
