Granatelli 6-Port Black Billet Aluminum Vacuum Manifold | 980104

Six Vacuum Connections. One Clean, Organized Setup.

Eliminate cluttered vacuum lines and simplify your engine-bay plumbing with the Granatelli Motor Sports Black Billet Aluminum Vacuum Distribution Manifold.

Whether you're building a turbocharged street car, upgrading a performance engine, or cleaning up a custom installation, this compact vacuum distribution block provides a centralized location for connecting multiple vacuum-operated components.

Constructed from billet aluminum with a sleek black finish, the manifold combines durable construction, versatile threaded connections, and a professional appearance suited for performance automotive applications.

Perfect for Performance Engine Builds

Modern performance vehicles often require several vacuum connections. Running individual hoses through multiple adapters and fittings can quickly create unnecessary clutter.

The Granatelli billet vacuum manifold creates a convenient central connection point that can help organize vacuum lines for compatible components such as:

• Boost gauges and vacuum gauges
• Fuel pressure regulators requiring a manifold pressure reference
• Blow-off valve reference lines
• Vacuum-operated accessories
• Custom turbocharged and supercharged engine configurations
• General-purpose automotive vacuum distribution systems

Note: Connections must be appropriate for the individual component and its required pressure signal. Some devices require dedicated lines or specific routing. Follow the component manufacturer's installation requirements.

Why Use a Vacuum Distribution Block?

A vacuum distribution manifold allows multiple compatible components to receive a manifold vacuum or pressure reference from a centralized source.

Instead of relying on numerous T-fittings and scattered hose connections, a central vacuum block makes it easier to plan, route, inspect, and maintain your vacuum plumbing.

Installation & Compatibility

The Granatelli vacuum manifold is a universal-style component. It is not limited to a particular vehicle year, make, or model. Installation may require appropriate NPT fittings, vacuum hose, adapters, and mounting hardware based on your application.

• Verify fitting compatibility with 3/8" NPT and 1/8" NPT threads.
• Use suitable thread sealing methods for tapered pipe threads.
• Confirm clearance and mounting position before installation.
• Ensure all unused ports are properly sealed.
• Verify that all connected components require compatible vacuum or pressure references.
• Do not use the manifold as a substitute for a brake booster vacuum reservoir or required safety-critical vacuum circuit.
