• Precision-engineered replacement for OE-style fit and function

Detailed Description

Sunsong 3401663 pressure hose assembly is built to replace a worn power steering pressure line with the correct fittings, length, and routing profile. The hose uses male O-ring connections at both ends, with 16 mm and 18 mm fitting sizes, and is constructed to handle hydraulic pressure in demanding steering systems. The steel tubing is zinc plated to help resist rust and corrosion from humidity, road salt, water, and grime.

This part cross-references Four Seasons 54930 and Gates 368510 for the same application. It is a practical choice for power steering hose replacement on Honda Civic applications where the original pressure line has developed leaks, cracks, or fitting wear. Sunsong 3401663 is also referenced by part number 3401663 when comparing steering hose options.

What It Helps Fix

• Power steering fluid leaks from a damaged pressure line
• Hard or inconsistent steering assist caused by hose restriction or wear
• Corrosion-related failure in the steel tubing section
• O-ring connection seepage at the hose ends
• Noise or loss of steering performance related to pressure loss

Installation Notes and Tips

Confirm end fitting sizes, hose length, and routing before installation. Inspect mating surfaces, O-rings, brackets, and nearby steering components for wear or damage before connecting the new hose. After installation, refill the system with the correct power steering fluid and bleed air from the system according to the vehicle service procedure.

Because this is a pressure line hose assembly, clean routing and secure attachment are important to prevent contact with hot or moving components. Verify leak-free operation after the system is pressurized.

Quality Assurance

Each Sunsong 3401663 hose is pressure tested before it leaves the factory to help ensure proper sealing and reliable operation. The hose is engineered to meet demanding pressure requirements and to provide long service life in steering system use.
