Manifold Vacuum Fittings and Plugs

Manifold Vacuum Fittings are used to connect to engine vacuum operated components such as power brake booster, transmission modulator, vacuum advance, HVAC components, etc. These are often overlooked or broken during attempted transfer when swapping engines or intake manifolds. Manifold Vacuum Fittings are available in a 90° or T-style fitting. The 90° fitting has a single 3/8" vacuum port and the T-style fitting has a 3/8" and 1/4" vacuum port. Both styles are available in zinc-plated steel or chrome-plated aluminum.

For those simply needing to plug the vacuum port in the intake manifold, order #30-1434. To plug the water ports in the intake manifold or water pump, order #30-1435.
