EGR vacuum routing??

73 F100 302-2v, 3spd manual.....Where does the vacuum line run from the EGR valve? I have run and read various searches without finding the answer. I have yet to find an open port that would be an obvious fix. Thanks

It should go to a ported switch in a water jacket on the intake. Then fron the switch to ported vacuum off of the carb.

There is what I guess may be a ported switch right between my coil and my thermostat. This switch, if I'm correct, comes off the intake manifold and is also one of the heater hoses. Off this heater hose connection is a piece with two vacuum ports on it. Is this what I'm looking for? It has two ports on it. Currently there is one piece of 4" hose looped from one port to the other, which doesn't look correct. Where is the port on the carb, driver or passenger side, front or back. Thanks

Yep, that sounds right. It only lets the EGR valve work when the engine it at operating temp and not when cold.

...and above idle and usually off - a dump valve present for WOT.

Thanks.. So the port nearest the end of the fitting itself goes to ported vacuum off the carb? The other port, the inner, goes to the EGR?
