Detailed Description

Sunsong 3402004 is a power steering pressure line hose assembly for Jaguar XJS models across the listed fitment range. The hose is built to exceed original equipment performance standards, with a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and tensile strength rated at 1,600 lb. High-grade steel tubing with zinc electroplating adds corrosion resistance against humidity, road salt, water, and grime, which is important for long-term service on Jaguar XJS steering systems. The 1/2 in. male inverted flare and 16 mm male O-ring end connections support the specified pump-end fitment, and the 65 in. length matches the application requirements for the Jaguar XJS pressure line hose assembly.

Common Problems This Hose Can Address

• Leaking power steering pressure line on Jaguar XJS models
• Cracked or deteriorated hose material from age and heat exposure
• Corrosion at the steel tubing or end connections
• Loss of steering assist caused by pressure-line failure
• Incorrect hose fitment at the pump end on 1979-1982 Jaguar XJS applications

Installation Notes and Tips

Verify the end fittings before installation: 1/2 in. male inverted flare on one end and 16 mm male O-ring on the other. Confirm the vehicle year and Jaguar XJS application details, especially the 1979-1982 pump-end note with 16 mm thread at the pump end. Inspect mating surfaces, flush the system as needed, and check for leaks after installation. This part number is 3402004.

Quality Assurance

Each hose is pressure-tested before it leaves the factory to confirm proper operation and installation readiness. Sunsong 3402004 is manufactured to meet demanding pressure-line service requirements for Jaguar XJS steering systems.
