Detailed Description

Sunsong 3401927 is a power steering pressure line hose assembly for 1997 Ford F-250, 1997 Ford F-250 HD, and 1997 Ford F-350 models listed with O-ring fitting applications. The hose is precision engineered for exact fit and uses high-grade steel tubing with a zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. With pressure ratings built above original equipment performance standards, this hose is suited for restoring stable steering fluid delivery in Ford F-250 and Ford F-350 steering systems.

This part cross-references Gates 353940 for the same application.

What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure line
• Steering noise caused by pressure loss in the hydraulic circuit
• Hard or inconsistent steering effort from restricted fluid flow
• Corrosion-related hose deterioration on older Ford truck steering systems
• Fitment issues when replacing an original O-ring style pressure hose

Installation Notes and Tips

Verify the fitting style, length, and routing before installation. This hose uses a 16 mm male O-ring end and a 1/2 in male O-ring end, so matching the original connection points is important for proper sealing. Inspect adjacent steering components, mounting points, and fluid condition during replacement to confirm the repair is complete.

Quality Assurance

Each Sunsong pressure hose is high-pressure tested at the factory before it leaves production. The hose assembly is engineered to restore original-condition wear items where required and to deliver dependable operation in the steering system.
