Anyone happen to have a vacuum hose diagram for 1974 Esprit with 350 2bl carb? It's a ZA California car if that makes any difference. Google search found plenty of 400 4bl but nothing to help me out. Thanks in advance! :D

Just scanning a few pages now. Does it/did it have the smog pump too?
In case you see similar diagrams, other 1974 350 2-bbl w/auto setups were YA-YB-YC, AA, ZA-ZB. Different cam on the ZA_ZB for California.
Not sure if these help.

Thank you thank you thank you! This is a great start. Mine is indeed a ZA California low compression 350.
Yes mine has the smog pump but no belt so I may remove it.
Much a appreciated. :-D

I also have the standard 350 2bbl diagram for if you have most removed or disconnected, but it isn't a lot less.

The top image helped me a lot! It validated what I have is mostly correct. The only difference is that the previous owner is getting vacuum to the distributer advance from the carb rather than from the thermal vacuum valve on the manifold as shown in the diagram but not sure if that's really a big deal. Also, one of the ports on that same valve that used to go to the air pump is blocked off so that's good since its doesn't even have a belt.
Thanks again!

A lot of the thermal vacuum switches and valves are no longer available or where once were specific, now covered by several broader settings. That may or may not affect original look or function, especially for those in CA.
