vacuum diagram for 7.4 v8
Have you checked in your engine compartment? Vacuum diagrams are normally posted either on the underside of the hood, front edge of engine bay or on top of the radiator.
I have checked their and its all faded off. I am installing my throttle body injection and trying to figure what vacuum lines hook up lines to it. I should have taken a picture before undoing them.
Yes that's always a good idea. I will try and find you a diagram.
