Information
Vacuum hose / Brake booster line
This OE Match vacuum hose / brake booster line is a replacement engine bay vacuum hose for Porsche 928 models from 1987 to 1995. It is associated with the LH-Jetronic intake hose system and is designed to match the original-style fitment and function within the brake booster vacuum circuit.
Fits:
Porsche 928 S4 1987 – 1991
Porsche 928 GT 1989 – 1991
Porsche 928 GTS 1992 – 1995
Diagram ref no 12
The hose carries vacuum from the engine intake system to the brake booster vacuum circuit. It connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum line arrangement, helping maintain the vacuum supply required for brake servo assistance and correct vacuum system operation.
Functions
• Connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum circuit
• Carries engine vacuum through the engine bay vacuum system
• Supports brake booster / brake servo vacuum supply
• Helps maintain correct vacuum pressure in the brake assist circuit
• Supports reliable brake pedal assistance
• Replaces cracked, split, hardened, or leaking original vacuum hoses
• OE Match replacement for Porsche 928 vacuum and brake booster system repair.
Why Replace This Part?
Vacuum hoses can become hard, brittle, cracked, loose, or split due to heat, age, engine bay conditions, and long-term vacuum load. A damaged brake booster vacuum hose can cause vacuum leaks, poor brake servo assistance, rough idle, running issues, or faults in connected vacuum-controlled systems. Replacing the hose helps restore proper sealing, reliable vacuum supply, and safe brake assist function.
When to Replace This Part
• The vacuum hose is cracked, split, brittle, or perished
• The hose is loose or no longer seals correctly
• Vacuum leaks are suspected in the engine bay
• Brake pedal assistance feels reduced or inconsistent
• The brake booster / servo vacuum circuit is being repaired
• The LH-Jetronic intake hose system is being serviced
• The vehicle is undergoing Porsche 928 engine bay or braking system restoration.
Where it fits on the car
This hose fits in the engine bay vacuum system of the Porsche 928. 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.
