Detailed Description

This Sunsong pressure hose is built for the steering system on the 2001-2004 Toyota Tacoma and is designed around the original routing and connection requirements of the vehicle. The hose assembly uses a 16 mm banjo fitting at one end and a 16 mm male inverted flare fitting at the other, with a 70.8-inch overall length and a power steering switch port. Sunsong 3402487 is manufactured with steel tubing protected by zinc plating to help resist rust, road salt, moisture, and grime.

This part cross-references Dorman - HELP 55103 and Gates 365845 for the same application.

What It Helps Fix

• Power steering fluid leaks from a damaged pressure line
• Steering noise caused by pressure loss in the hydraulic system
• Corrosion on the original steel hose assembly
• Cracked, fatigued, or worn hose sections
• Hard steering caused by restricted fluid flow

Installation Notes and Tips

Confirm the fitting types, hose length, and switch port layout before installation. Inspect related seals, mounting points, and surrounding steering components for wear or contamination so the replacement hose can be installed on a clean, properly routed system. Verify that the line follows the original path and clears heat sources and moving parts on the Tacoma.

Quality Assurance

Each Sunsong 3402487 hose is pressure-tested at the factory before shipment. The assembly is engineered to exceed original equipment performance standards for pressure capacity and durability, with a maximum working pressure of 1,500 psi, burst pressure rating of 8,700 psi, and tensile strength of 1,600 lb.
