Dorman Vacuum Storage Canister replacement 47076 — direct-fit OEM-style reservoir for brake booster & HVAC vacuum

The Dorman 47076 Vacuum Storage Canister is a direct-fit replacement vacuum reservoir engineered to restore proper vacuum capacity and fit the original mounting and hose connections on specified vehicles.

This vacuum storage canister from Dorman is designed to replace a missing, cracked, or failing original reservoir. Constructed from durable materials and manufactured to match OEM fit and connection points, it provides the stored vacuum volume your vehicle’s systems depend on. Installers and DIYers can rely on this part when troubleshooting vacuum-related issues that impact brake boosters, HVAC controls, or evaporative emissions systems (EVAP), depending on vehicle application.

How does this canister restore vacuum-dependent functions?

By supplying a stable reserve of vacuum, the canister prevents sudden drops in vacuum pressure when engine vacuum fluctuates. That reserve helps components that require steady vacuum continue functioning during transient conditions like acceleration or load changes.

• Stores vacuum to smooth supply during engine load shifts
• Maintains vacuum for brake booster assist and control actuators
• Prevents intermittent loss of vacuum-operated HVAC or EVAP valves
• Direct-fit connections reduce installation errors
