Detailed Product Overview

This Sunsong power steering pressure line hose assembly, part number 3401764, is built to restore hydraulic steering flow on Volkswagen Corrado, Golf, Jetta, and Passat models listed in the fitment data. The hose is precision engineered for exact fit and uses male O-ring ends in 16 mm and 18 mm sizes to match the specified steering connections.

This part cross-references Dayco 71280 and Gates 3740 for the same application.

What This Hose Helps Address

• Power steering fluid leaks from a worn pressure line
• Steering noise caused by pressure loss in the hydraulic circuit
• Heavy or inconsistent steering effort
• Corrosion damage on the original steel line
• Fitment issues when replacing an aging Volkswagen steering hose

Installation Notes and Tips

Verify the pump-end and rack-end fitting sizes before installation. This hose does not include a bracket or PS switch port, so confirm the vehicle’s original routing and connection layout against the listed fitment and notes. For 1993 Volkswagen Passat applications, use the listing note for O-ring fitting at the pump end.

Quality Assurance

Each hose is pressure tested before it leaves the factory to confirm proper operation and installation readiness. The pressure rating, burst rating, and tensile strength are published performance specifications for this Sunsong 3401764 hose assembly.
