Went and pulled out a box of take off parts a shop gave to the previous owner. One was a vapor separator. Compared to the one I just got and only difference I can see is the bracket has two dimples on one and only one on the other.

Next rockauto order I’ll grab one of those. Have to see how each I have compare, can check the nipple size too. Will have one coming off the car at some point so four will be on hand.
