Product Details

This Sunsong power steering pressure line hose assembly is built to restore pressure-side steering fluid flow with exact-fit dimensions and OE-style connection points. The 3401877 uses male O-ring fittings at both ends and combines CSM hose material with steel tubing for durability in demanding underhood conditions. It is a direct-fit solution for Jaguar XJ6 and Jaguar Vanden Plas models from 1988 through 1994, making it a practical choice when replacing a worn or leaking pressure hose.

This part cross-references Gates 355590 and Dorman - HELP 80372 for the same application.

Common Problems This Part Can Address

  • Power steering fluid leaks from a cracked or worn pressure hose
  • Loss of steering assist caused by pressure line failure
  • Noise or stiffness in the steering system related to fluid loss
  • Corrosion damage on the original steel tubing
  • Poor sealing at the hose ends due to aged O-ring connections

Installation Notes and Tips

Verify the end fitting sizes before installation: 14 mm male O-ring on one end and 16 mm male O-ring on the other. Confirm hose routing matches the original layout on the vehicle and inspect adjacent steering components for wear, contamination, or fluid residue before completing the repair. This hose assembly does not include a bracket or PS switch port.

Quality Assurance

Each hose is pressure-tested before it leaves the factory to help ensure proper operation after installation. Sunsong states that this pressure hose line is built to exceed original equipment performance standards, with corrosion-resistant zinc-plated steel tubing for added durability in harsh road and weather conditions.
