Part number 3403283 is a practical replacement choice when servicing the steering system on Ford Super Duty trucks that require 16 mm fittings.

What This Part Helps Address

• Steering fluid leaks at the pressure line
• Loss of hydraulic steering assist
• Damaged or corroded steel hose sections
• Improper fitment from worn or incorrect replacement lines
• Noise or inconsistent steering feel caused by pressure line wear

Installation Notes and Tips

Verify hydroboost-to-gear routing, 4-bolt valve housing configuration, and 16 mm fitting sizes before installation. Inspect mating seals, mounting points, and nearby steering components for wear or contamination before connecting the new line. Confirm the hose follows the original path to avoid contact with heat sources or moving parts.

Quality Assurance

Each Sunsong pressure hose is subjected to a high-pressure quality test before leaving the factory. The assembly is built to exceed original equipment performance standards for pressure, burst resistance, and tensile strength, supporting reliable operation in the listed Ford Super Duty applications.
