My lower rail injectors are being pushed out and they leak, like in this video:
I have the little rubber spacers on the end of them. They seem to get pushed out about the thickness of the fuel distributor insulator, would it be ok to leave the insulator out? It wasn't even connected to anything when I took it out. Any help is appreciated.

Edit: Doesn't fit properly without insulator. Need new rubber spacer? and should the insulator be connected?

It looks like maybe the cup seals on the other end of the injectors where they sit into and seal in the iron ports are missing. When that’s all in place and rail is bolted down it’s all tightly squeezed together and sealed. It looks like the pressure just pushed the injector down and out of the rail, which it can’t do if those cup seals are in place (large black rubber seals in the bottom two pics below).

I do have those seals in, I ordered some new ones to try in case mine are flattened or something. Is there anything else that could be causing this?

I would make sure you have the reducers ( parts team is talking about) as well as both o-rings on the top and bottom of the injector. Like he said, once its bolted down it's pretty sandwiched into place.

Went and mocked it up on my car real quick for some pictures, injectors have everthing attached to them, but there's still a gap.

Are you sure those are the same length as the OE injectors? There has to be something off on length, thickness, etc. for that to happen.

I believe they are the oe injectors
