The power steering pressure line transfers hydraulic fluid under pressure between the power steering pump and steering rack system. This hydraulic pressure assists steering movement, helping provide smooth, controlled and responsive steering operation.

Functions
• Carries pressurised power steering fluid through the steering system
• Connects power steering components in the hydraulic circuit
• Supports smooth and assisted steering operation
• Helps maintain correct steering system pressure
• Replaces leaking, corroded, cracked or damaged original pipework
• Helps prevent power steering fluid loss and steering assistance failure
• OE Match replacement for correct fit and reliable steering performance

Why Replace This Part?
Power steering pressure lines are exposed to high hydraulic pressure, heat, vibration, road dirt and corrosion. Over time, the pipe or hose sections can crack, leak, rust, swell or fail at the fittings. A worn pressure line may cause fluid leaks, whining noises from the pump, heavy steering or loss of power steering assistance. Replacing the line helps restore proper hydraulic pressure and protects the steering system from damage caused by low fluid levels.

When to replace
•  Power steering fluid is leaking from the pipe or fittings
•  The line is corroded, cracked, swollen, kinked or damaged
•  Steering feels heavy or inconsistent
•  There is a whining or groaning noise from the power steering pump
•  Fluid level drops repeatedly after topping up
•   The steering rack or power steering pump is being replaced
•   The vehicle is undergoing steering system repair or maintenance
•   As preventative replacement when old hydraulic lines show signs of wear.

Where it fits on the car
This pressure line fits in the hydraulic power steering system on Porsche 987.2 Boxster and Cayman models. It forms part of the steering fluid circuit, routing pressurised fluid between the steering pump and steering rack area, depending on vehicle specification.
