Vacuum guage on a Gen V 7.4L
 

Hi, anyone know if / where I can plug a vacuum guage to the manifold or anywhere else to tune my carburetor? It's on 1992 Gen V , 454. Thanks

Is there a plug in the rear base of the carb ?

I'll need to check it's an edelbrock, and most ports are not even on this carb since it's a 1410 marine....they've deleted the ports on the front of it , if not in the back as well.

any plugs in the intake?
