I have a 73' F100 With a 302 aand a C4 tranny.

My Question is....
There are two metal vacuum lines that come up from behind the motor from the tranny. I was told that they go into the my intake. I'm using a Edelbrock #2121 Intake. Where do they go and what type of fitting do I need.

Thanks Ya'll

right now one goes to the back of my Edelbrock #1406 600cfm. Somebody told me that it should go to the intake. And that the port on the back of the carb was for power brakes.( old school dont have those )
The other is attached to the retard port on my vacuum advance. which is going to be replaced soon. ( ordered wrong one )but the correct one only has a single vacuum port and it goes to the timed vacuum port on my carb.


thanks again ya'll
