Product Information
This a high-quality replacement reservoir stores vacuum created by the engine or vacuum pump, providing a steady supply of vacuum to systems such as brake boosters, emissions control, and actuators even under engine load or varying vacuum conditions. It’s moulded from durable plastic with designed internal volume, mounting bosses, and port locations matching the original Porsche part (replaces 99311014002 / 99311014003 / 0PB129093).
Fits:

Diagram ref no 6
Engineered to OE standards, this unit replicates the original shape, mounting points, port alignment, and internal volume. Its material resists heat, oil vapor, and pressure cycling to provide reliable vacuum buffering over long-term use.
Over time, the vacuum reservoir can crack, leak, or lose internal sealing, leading to:
• Reduced braking assistance
• Malfunction of intake or exhaust actuators
• Check-engine lights caused by vacuum faults
• Rough idling or loss of power under load
Replacing the vacuum reservoir restores full vacuum stability and ensures proper operation of all connected systems. This is especially important when diagnosing brake booster failures, emissions issues, or vacuum leak codes.
