Coyote Swap: Whipple Boost reference

[migg400]

I need a little help with routing vacuum hose from the fuel pressure regulator (boost reference port) to the blower for boost reference and proper fuel pressure control. I am using an Aeromotive fuel pressure regulator and a Whipple 2.3 kit for 2011-14 Coyote's. I swapped a coyote into my 67 Fastback with a 5spd trans. My thought was to use a blower elbow for the Automatic cars and use the vacuum connection on the elbow that would be used for the brake booster? I really can't find much info on this, so any help here would be greatly appreciated!
