I did a full 2012 5.0 swap into my 2007 Mustang. Looking for a diagram for the vacuum hoses. What connects to the rear vertical port on the back of the stock intake manifold?

Funny enough, I have the same problem. 97 GT coyote swap with a 2013 F150 motor. I think this is the port that needs to have reference to your fuel pressure, but I can't find anyone who makes a proper line

Hey bro, don’t know if you found the answer or not but I’ve been going crazy trying to find it too. Recently took the motor out and looked inside and it looks like a closed up line lol, don’t think it has a purpose

I have a Coyote in my 2012 F150. I'll check tomorrow and see if I can see it and report back.

Can infact confirm port on rear drivers side is open and uncapped and I've put 115k miles on my truck like this since purchased 7 years ago.
