Have a '77 F 150, 460 non-catalyst, CA emissions, no A/C, A/T. The PO rigged a lot on this truck and somehow got the truck smogged when I bought it. Anyway, I have fixed the majority of things he rigged, but I need a vacuum hose diagram to figure that aspect out.
I have searched extensively on FTE trying to find the diagram for my specific instance. Fasthauler tried to help but the diagram he has does not have all the hoses my truck has. His diagram is the one I found posted on the web from Mitchell on Demand.
Does anyone have this elusive diagram or can direct me where to find one?
Went to the Riverside Public Library yesterday. They have a large collection of Mitchell, Motors, and Chilton professional repair manuals. I found the vacuum schematic for my truck.
However, after studying the schematic, I notice that the "green" (color as designated in the schematic from the Motors manual) hose that is supposed to run from the top of the vacuum amplifier to the venturi port on the back left of the carburetor runs to manifold vacuum instead. In its place is a hard line that is paired with the hard line for heating the automatic choke. It looks factory to me. Any ideas on this set up?
