Information
Vacuum hose / Brake booster line
This Genuine Porsche vacuum hose is used on Porsche 928 models within the intake/vacuum hose system and is associated with the brake booster vacuum circuit.

Diagram ref no 12
This hose is commonly described as the hose from the left intake side cover to the brake venturi “Y”.
Functions
• Routes vacuum through the engine intake/vacuum system
• Supports correct brake booster vacuum supply
• Helps maintain proper vacuum assistance for the braking system
• Connects the left intake side cover area to the brake venturi “Y” connection
• Helps prevent vacuum leaks that can affect idle quality and engine running
• Maintains correct factory hose routing and fitment
• Replaces aged, brittle, cracked or leaking original vacuum hose
• Provides OE Porsche fitment for the 928 vacuum system.
Why Replace This Part?
Vacuum hoses become brittle, cracked, hardened or loose with age and heat exposure. A leaking vacuum hose can allow unmetered air into the system, which may cause rough idle, poor running, hesitation or reduced brake booster vacuum performance. Replacing the original hose with a Genuine Porsche OE vacuum hose helps restore the correct vacuum circuit, supports brake booster assistance and keeps the engine vacuum system operating as intended.
When to Replace This Part
• If the hose is cracked, brittle, split or hardened
• If there is a vacuum leak or hissing noise
• If the engine has rough idle or poor running caused by unmetered air
• If brake assistance feels reduced or inconsistent
• During intake, vacuum system or brake booster vacuum repairs
• During engine bay restoration or preventative maintenance
• When replacing old, non-original or incorrectly routed vacuum hose
• Before recommissioning a Porsche 928 that has been stored long-term.
Where It Fits on the Car

It is associated with the LH-Jetronic intake hose system and connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum circuit. Parts diagrams show this hose as diagram reference no. 12 in the LH-Jetronic hose section.
