Help identify part...
 

I am not 100% sure this is a left over from working on my car but... if it is I would like to identify where it goes. It was left over after doing valve timing, fuel injectors, having the alternator out etc. on my 3.2L in a 73 car.

It is a hard, black plastic and for sice you can reference that is is sitting on a post it note pad. Any insight is appreciated.
