Need some assistane with the following piece of the fuel system that I have no idea as to what it is.

Id on vacuum chamber is EITE-9D448-HIA. I will attempt to insert a photo but relatively computer inept.

A sage once stated, "doing the same thing over and over, while expecting a differant solution is insanity."

 

That , my friend , looks to be an EGR plate . If at all possible , Smog rules , Delete it . My 78 may or may not have the egr blocked , I'll never tell !

 

Thanks I've been searching for a Thermactor, with no luck.
