FIC 850s..Something missing?

[ILLiCliPSE]

Is there anything missing from my FIC 850s? Such as an o-ring on the bottom? This pic is of a RC injector (left) and a FIC injector (right). Shouldnt there be an o-ring at the bottom just like the RC injector does? Or is that big rubber piece on the FIC injector all it needs?

I know my PTE 680's have an o-ring there.

Those are FICs in the pic

The injector all the way to the right is how it should look.

Upper o-ring, injector insulator, then the lower seal at the bottom.

You have the top piece on the bottom.

The lower black rubber o-ringis for where the injector seats into the head. He has everything correct.

Imaterial, the o-ring he is missing is the viton seal on the other side of the injector the side that inserts in the rail, not the head.
