Detailed Description

This Sunsong pressure hose assembly is made for Nissan D21 steering systems that require a banjo-to-banjo pressure line with a power steering switch port. The 3401976 hose uses steel tubing with zinc plating to resist rust and corrosion from humidity, road salt, water, and grime, while the hose construction is specified to handle demanding hydraulic pressure conditions.

For buyers searching for a 1990 Nissan D21 power steering pressure hose, 1991-1993 Nissan D21 steering hose replacement, or a 1990-1993 Nissan D21 banjo fitting pressure line, this assembly matches the listed application and dimensions. The Sunsong 3401976 is also cross-referenced to Four Seasons 91693 and Gates 370070 for the same application.

What It Helps Resolve

• Power steering fluid leaks from a worn pressure line
• Loss of steering assist caused by hose pressure failure
• Corrosion-related damage to the original steel line
• Fitment issues from an incorrect banjo fitting or hose length
• Electrical switch-port replacement needs on the pressure line

Installation Notes and Tips

Verify the 16 mm banjo fittings, 71.8 in. length, and PS switch port before installation on your Nissan D21. Inspect mating surfaces, seals, and adjacent steering components for wear or contamination so the new hose can seat correctly and maintain proper hydraulic pressure.

Quality Assurance

Each Sunsong pressure hose is pressure-tested before it leaves the factory. The hose is specified with a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and a tensile strength of 1,600 lb for consistent performance in service.
