Detailed Description

Sunsong 3403240 is a power steering pressure line hose assembly for the BMW Z3, covering 1997-2002 model years. It is engineered to meet or exceed original equipment performance standards, with a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and a tensile strength of 1,600 lb. The hose uses CSM material and precision-formed steel tubing with zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. This BMW Z3 power steering pressure hose is built for direct replacement service and is identified by part number 3403240.

This part cross-references Gates 352411 for the same application.

What It Helps Fix

• Power steering fluid leaks from a worn pressure hose
• Loss of steering assist caused by pressure-line failure
• Corrosion-related hose deterioration on BMW Z3 steering systems
• Cracked or fatigued hose material from age and heat exposure
• Improper steering response caused by hydraulic pressure loss

Installation Notes and Tips

Verify the banjo and male O-ring end fittings, hose length, and routing before installation. Inspect mating surfaces, seals, and adjacent steering components for wear or contamination before connecting the new hose. Confirm the line follows the original path on the BMW Z3 to avoid contact with heat sources or moving parts.

Quality Assurance

Each hose is high-pressure tested at the factory before it leaves production. Sunsong builds this pressure line to restore original-condition function with corrosion-resistant materials and exact-fit engineering for 1997-2002 BMW Z3 applications.
