Injector popping out of Line
I keep having an issue of a primary injector popping out of the fuel rail. It drops down into the center plate intake hole way too far. Is there supposed to be space for it to fall in like that? I just rebuilt the engine and all of the injector seals are new.
I've swapped the injectors and the problem is always at the front rotor hole no matter what injector is in there.
Not my video but this is the problem. I understand he said it was a clogged injector in the comments but I don't understand why it wouldn't follow the injector if that was the case.

Is this really how these injectors are set up? Theres no spacer in the bottom to prevent this? It seems like it's a big point of failure. I remember the lower seals staying in the engine when I removed the injectors but I don't remember how far down.
Any input helps. Thank you.
This is the last step before I can get this thing to finally run and its frustrating that I'm so close and falling flat.

I'm at a loss because this doesn't seem to be a common problem so I have no feedback. And for the same reason I feel like I'm missing something obvious.

He had the correct parts more than likely and was doing something wrong, but you can get those parts almost anywhere. When it's installed fully the fuel rail pushes them down fully and seals the face. It doesn't seal around the perimeter. My Injector Dynamics race injectors only have a flat face O-ring on the end that only seals on the face. The tip of the injector sticks through a center hole down into the port to keep it all aligned.
