I found this part located inside the air cleaner on my sons' 1973 Mustang fastback. It has a 351 Cleveland in it. I've switched over to a RAM air hood. This part was on the inside of the old air cleaner. It had 2 vacuum lines running to it that had been cut off. I believe it's a air cleaner temperature sensor, but not 100% sure. So, what is it? Do I need it? What does it do? Where do the vacuum lines run to ? Lastly, if I need it, any idea where I can pick up a new one? Thanks to all!!
