Can someone help me identify what parts these are...

[fbody4life]

I just got my fuel pump in the mail yesterday for my 1995 and plan on trying to install it tomorrow via the access door method.

So here is what it came with...



So there were 4 pieces in the box. I am just not sure what 2 of them are for (I'm sure I would figure it out once I started, but wanted to post anyways...)

What is the large rubber o-ring for, is it the new fuel tank seal after I'm done installing the new pump?

Also what is the small black piece and where do I use it?

This one...
