I have a 79 f100 302 that i would like to reinstall the egr and i need to know how to run the vacuum lines. Any diagrams would be appreciated.

 

There were several setups in later years, but the basic setup is this: ported vacuum runs from the carburetor to a ported vacuum switch in the intake or thermostat housing; the other side of the switch runs to the EGR valve.

 

Thanks for the reply thants what i was gona do.
