Review on 🖤 Enhanced Performance: Vibrant 2691 Black Anodized Aluminum Vacuum Manifold by Mark Gardner

Love Vibrant products. Looks great and works even better. Helped aesthetically clean my vacuum system and my vacuum readings are more stable and accurate. I didn't find it in the description so I'm adding it here. 3/8" NPT inlet, 1/8" NPT outlet. Be sure to use thread paste or PTFE tape to achieve a proper seal. Finally, I connected a tee to my brake booster line for the main vacuum source. I would probably recommend adding a separate half inch connector to your intake manifold and leaving the amp alone, but it worked fine in my case.
