Black Steel Vacuum Sys tem Reservoir Tank

The Black Steel Vacuum System Reservoir Tank (model R9970) from Racing Power Co-Packaged is an essential component for any engine running a mechanical fuel pump or vacuum-operated accessory system. This reservoir captures and stores vacuum pressure generated by your engine, allowing consistent operation of brake boosters, emission control systems, and other vacuum-dependent equipment. Whether you're building a high-performance street engine, restoring a classic muscle car, or maintaining a daily driver with upgraded components, a dedicated vacuum reservoir ensures stable system performance across varying engine speeds and load conditions.

Constructed from durable black steel, this vacuum tank is engineered to withstand sustained pressure cycles without degradation or failure. The compact cylindrical design measures 5.65 x 5.4 x 8.3 inches and weighs just 2.32 lbs, making it ideal for tight engine bay installations where space is limited—a common reality in vintage restorations or heavily modified modern builds. The welded steel construction provides reliable containment of vacuum pulses while resisting corrosion from engine heat and moisture exposure. Vacuum reservoirs work by buffering pressure fluctuations, preventing pressure drops that would otherwise cause weak brake response, rough idle characteristics, or inconsistent operation of emission control valves and actuators.

This tank is ideal for engine builders, restoration enthusiasts, and performance mechanics installing custom fuel systems or upgrading factory vacuum circuits. Installation requires basic plumbing—connect the tank inlet to your engine's vacuum source (typically the intake manifold) and run outlet lines to your brake booster and other vacuum-operated systems. Verify your existing vacuum line diameters before purchase to ensure proper hose adapter compatibility. Racing Power Co-Packaged components are trusted throughout the hot rod and restoration community for consistent quality and reliable long-term performance in demanding automotive applications.
