• Corrosion-related hose damage from moisture, salt, or grime
• Pressure loss in the steering hydraulic circuit

Installation Notes and Tips

Verify the end fitting size and type before installation: this hose uses 16 mm swivel O-ring fittings at both ends and measures 62.5 inches in length. Inspect mating ports, seals, and surrounding steering components for wear before installing the new line. Proper routing is important to avoid contact with hot or moving parts, and the original hose path should be followed closely for clearance.

For Ford F-150 pressure hose replacement work, confirm the vehicle’s steering line configuration matches the part before removal of the old assembly. The Sunsong 3404154 is factory tested to support trouble-free installation and operation when used on the correct application.
