How many of us are there? Owners of Dodge based RV's?

I have next question ;-) At my Carter Thermoquad i had a vacuum line from the carburetor to the air pump diverter valve. Now at my Edelbrock 1406 carburetor i have 2 vacuum ports. Timed vaccum port and manifold vacuum port. I use the timed vacuum port for the distributor and the manifold vacuum port is free. Should i connect the vacuum line from the air pump diverter valve to the manifold vacuum port at the carburetor or should i deactivate (cork) the vacuum line from the air pump diverter valve?
