This pressure hose assembly is engineered to match the original routing and connection points for the Ford F-250 Super Duty and Ford F-350 Super Duty hydroboost system. Sunsong 3403282 uses high-grade steel tubing with zinc electroplating for added resistance to corrosion from humidity, road salt, water, and grime, while the hose construction is built for long service life under steering-system pressure.

Common Steering Problems It Can Address

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged or worn hose
• Cracked, rusted, or corroded steel tubing
• Incorrect fitment on hydroboost-to-gear steering routing
• Noise or pressure loss caused by a failing pressure hose assembly

Installation Notes

Verify the vehicle uses hydroboost steering with a 3-bolt valve housing and the listed 16 mm and 18 mm fittings before installation. Confirm hose routing, connection style, and length against the original part to ensure proper alignment on the Ford Super Duty steering system. This part cross-references Gates 366209 and Four Seasons 55421 for the same application.

Quality Assurance

Each Sunsong 3403282 hose is pressure tested before it leaves the factory to help ensure proper operation after installation. The assembly is precision engineered for exact fit and built to restore worn steering-line components to original condition.
