Vacuum Manifold Black

The Vacuum Manifold Black from REDHORSE PERFORMANCE is a precision-engineered component designed for serious engine builders and tuners who demand reliable vacuum distribution across multiple accessory systems. This compact manifold serves as a central junction point for vacuum-operated devices—from brake boosters and emissions control systems to fuel pressure regulators and HVAC controls—making it essential for custom engine builds, carburetor conversions, and performance modifications where OEM manifold ports are insufficient or inaccessible.

Built from durable materials with a hardened black finish, the vacuum manifold features multiple inlet and outlet ports that allow you to split a single vacuum source into several controlled branches without pressure loss or collapse under engine load. The 5.45 x 1.65 x 5.95-inch footprint is compact enough to mount in tight engine bays while offering the flow capacity needed for high-vacuum applications. REDHORSE PERFORMANCE's attention to port sizing and internal bore finishing ensures minimal turbulence and consistent vacuum signal delivery—critical for precise carburetor tuning, proper brake booster function, and stable emissions system operation.

This vacuum manifold is ideal for street rods, vintage muscle car restorations, and carbureted performance engines where factory vacuum trees are unavailable or inadequate. It works seamlessly with mechanical fuel pumps, adjustable fuel pressure regulators, and aftermarket vacuum-operated components common in classic and modified powerplants. At just 0.63 lbs, installation is straightforward using standard hose barbs and clamps; ensure all connections are tight and free from kinks to maintain signal integrity across all downstream systems.
