Built for Pressure and Corrosion Resistance
This pressure hose assembly is rated for a maximum working pressure of 1,500 psi, with an 8,700 psi burst pressure rating and 1,600 lb tensile strength. The tubing uses high-grade steel with zinc electroplating to help resist rust and corrosion from humidity, road salt, water, and grime. Sunsong 3401654 is precision engineered for exact fitment and is quality tested before it leaves the factory.

Common Steering Problems It Can Address
- Power steering fluid leaks from a worn pressure hose
- Steering noise caused by pressure loss in the hydraulic line
- Hard or inconsistent steering response on Nissan D21 and Pathfinder models
- Corrosion-related hose deterioration in exposed underhood conditions
- Fitment issues from an aging hose with damaged banjo connections
Installation Notes and Tips
Confirm the vehicle’s build date before ordering, especially for the 1989 Nissan Pathfinder application listed through 10/31. Match the 16 mm banjo fittings and verify the PS switch port location against the original hose before installation. Inspect surrounding seals, brackets, and steering components for wear so the replacement hose can be installed on a clean, serviceable system.
Quality Assurance
Sunsong pressure hoses are factory pressure tested for installation confidence and consistent operation. The hose construction, steel tubing, and corrosion-resistant finish are selected to support long-term service in steering systems that demand stable hydraulic pressure.
