Can anyone point me in the correct direction of where I can get a vacum line diagram for my 350 2bbl 1968 FB (No A/C). I am a little confused as to how many lines I should have and where they should terminate....I have a five port Thermostic vacum valve that has only 2 lines going to it...One line to the rear of the carb and the other to the Distbutor.

I appreciate any help and or advice.

On this site, look up service bulletins, emissions and you will find the routing for the hoses. Is your car a man or auto? If it's an auto, the retard function is eliminated and the bulletin shows how to re-route the hoses

Its auto...Original tranny. How many vacumes hoses should their be then?

Thanks for your help.
