Installation Notes and Tips

Verify end fitting sizes, hose length, and vehicle-specific notes before installation. This Sunsong 3401843 hose is listed with male inverted flare ends and no bracket or power steering switch port, so matching the original routing and connection style is important for proper installation. This part cross-references Gates 353700 for the same application.

Quality Assurance

Each hose is pressure tested before it leaves the factory to confirm sealing and operation. Sunsong designs this pressure line hose assembly to meet or exceed original equipment performance standards for long-term service on Buick, Oldsmobile, and Pontiac steering systems.
