Power steering pressure hose. Porsche 928 1985-90

92834744708/1

Product Information

Power steering pressure hose. Pump To Rack.
It carries high-pressure hydraulic fluid from the power-steering pump to the steering rack, enabling the assisted steering function that makes driving smoother and more controllable - especially at low speeds or when manoeuvring.

Fits:
For LHD (Left Hand Drive) cars
Porsche 928 1985 - 1990

Diagram ref no 17

• System: Power-assisted steering - connects pump to steering rack (pressure line)

• Typical Usage: Replacement of old or worn pressure hoses, power steering overhaul or maintenance, repair of fluid leaks or loss of steering assist.

Over time, the factory power steering pressure hose can degrade due to heat, hydraulic stress, and age - leading to cracks, swelling or internal weakening. A failing hose may leak fluid, lose pressure, or collapse under load, causing hard steering, noisy pump operation, or complete loss of hydraulic assist. Replacing it with a correctly specified hose ensures reliable fluid delivery, restores steering assist performance, and protects other steering system components from undue stress.

Aging power steering hoses can harden, crack, or leak due to heat and hydraulic stress. A failing hose may lead to:
• Loss of steering assist
•  Fluid leaks and pump starvation
•  Steering noise or inconsistent steering feel
• Potential pump or rack damage due to pressure loss.
Replacing it with a Genuine Porsche hose restores secure hydraulic operation and maintains the car’s intended steering performance.

Professional Installation Required
Each hose section is supplied with a dedicated crimp sleeve. Installation must be carried out by a professional to ensure correct crimping and secure sealing.

Complete OEM replacement hoses are expensive. This repair kit provides a practical and cost-effective alternative by replacing only the flexible rubber hose sections while allowing you to reuse the original steel pipe assemblies.

What This Repair Kit Does

This kit replaces the flexible sections of the low-pressure power steering return line. The return hose carries fluid back to the reservoir and operates at low pressure, making it suitable for high-quality reinforced silicone replacement hose.

By installing this repair kit, you can:

• Eliminate leaks from aged rubber sections
• Retain the original factory steel hard lines
• Avoid the cost of complete OEM hose assemblies
• Restore safe and reliable power steering operation

Why Upgrade to This Silicone Repair Kit?

Significant Cost Saving
Original Porsche 928 power steering return hoses can be very expensive. This repair solution allows you to refurbish the existing assembly at a fraction of the cost.

High-Strength Silicone Construction
Manufactured from very strong, heat-resistant silicone, the replacement hose sections provide improved durability over ageing factory rubber.

Designed Specifically for 928 Applications
This kit is engineered to suit the correct hose diameters and routing used on Porsche 928 S2, S3, S4, GT and GTS models.

Safety Reminder
Power steering fluid is flammable. It is important to regularly inspect return hoses and address leaks immediately to reduce fire risk within the engine bay.
