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.

This tank is ideal for engine builders and restoration enthusiasts looking to enhance the performance of their vehicles. 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. With its reliable design, this vacuum reservoir is a valuable addition for anyone involved in performance mechanics or custom fuel systems.
