Compatible with 1998-2003 Jaguar Vanden Plas, reservoir to pump, as well as 1998-2003 Jaguar XJ8 and 1998-2003 Jaguar XJR, reservoir to pump.

Key Features

• Return hose for the power steering reservoir-to-pump line
• Rated for a maximum working pressure of 250 psi
• Suitable for low-pressure, high-temperature operation
• High-grade steel tubing with zinc electroplating for corrosion resistance
• Precision-engineered fit for direct replacement service
• Includes required brackets, grommets, heat shields, bushings, and protective sleeves where applicable

Detailed Description

Sunsong 3404716 is built to restore the reservoir-to-pump return path in the power steering system on Jaguar Vanden Plas, XJ8, and XJR models from 1998 through 2003. The hose uses steel tubing with a zinc-coated finish to resist rust and corrosion from humidity, road salt, water, and grime. Its exact-fit design supports proper routing and replacement of worn wearable components in the steering hose assembly.

This part cross-references Gates 39112 for the same application.

Common Problems This Part Can Address

• Power steering fluid seepage at the return hose
• Corrosion on the original steel line
• Cracked or deteriorated hose sections
• Improper routing or fit from a worn replacement line
• Noise or steering performance issues caused by fluid loss

Installation Notes and Tips

Verify the reservoir-to-pump routing before installation and compare the original hose shape, bracket locations, and connection points to the new part. Inspect adjacent steering components for wear, contamination, or corrosion while the system is open. Use the vehicle-specific fitment details for 1998-2003 Jaguar XJ8, XJR, and Vanden Plas applications to confirm the correct replacement path.

Quality Assurance

Sunsong manufactures this hose to meet original equipment performance standards for return-line service. The steel construction and zinc plating are selected to improve durability in harsh underbody conditions, and the precision-engineered fit supports consistent replacement on Jaguar steering systems.
