Hello all, looking for suggestions or information on what everyone is doing to cap their vacuum port on the manifold I am using a double action fuel pump, so I do not need this for wipers I would like to still have access to the port for tuning with vacuum gauge I would think a ball valve and barbed fitting with vinyl cap, but that may look clunky
What's wrong with what you're doing now? It looks simple and effective. Jerry

The vacuum pump delivers a smaller vacuum than the manifold. It is meant to augment the vacuum when it is low in the manifold. The pump will not deliver a lot of vacuum at low RPMs. At least, that is how GM explains it. I think when I had mine it would deliver about 11" at a higher RPM.
