Yes you do!, they sit inside the center plate and seal the injectors and the plate together. where have yours gone?? I just replaced both of mine, it cost me all of $10.

They're not O rings per se, but they are round black rubber rings. They could still be in the bore of the engine block.

well i just replaced the fuel pulsation dampener and when we pulled the fuel rail up, there was only 1 O ring... and it was mangled to ****.... I have always had this vacume leak sound and we could not find where it was coming from. is it possible this is the cause of the leak if i was missing 1 of the rings?
