Where oh where is the vacuum tap on a fuel injected 5.0 (302)? I spent all day trying to track down a port that I could connect a vacuum guage to and I can't find one. Can someone point me in the right direction?

Thanks.

On my EFI 351 there is a vacuum "tree" about in the middle (front to rear) of the upper intake. The intake runners curve over the passenger side valve cover and the vacuum point is pointing almost vertical between the middle runners on the drivers side.
There should be a tap in the very back of the upper intake where the PCV tube is connected.
You could also tee into the supply tube to the solenoids that operate the thermactor valves.
