fuel pressure regulator questions, vaccuum port?

[aandrave]

I was going to get an adjustable fuel pressure regulator but I didn't know if the mustang uses a port for vaccuum (nissans use 1:1 and I saw a universal aeromotive one with 1:1 port) or an fpr without a vaccuum port (the ones that bolt on the fuel rail don't look like they have a provision for one).
