Default issues with STi Pink injectors

I got a set of injectors with out any kind of rings or O-rings. and to add to it, one of them is missing the O-ring retainer ring at the top of the injector. Now correct if im wrong but my understanding of the injector rings are as follows: from top to bottom, retainer ring, O-ring, injector ring, injector grommet/ring.

If anyone has any insight on this please help me out, my questions are as follows:

1. Can I still run the injector with just the O-ring and injector rings or would it leak with out the O-ring retainer ring?

2. are the rings made of rubber or hard plastic? the ones on my blue injectors crumble to pieces when I tried to remove them to use on the pinks.

3. will the DW injector rings kit work for STi pinks?
