Detailed Description

Sunsong 3401708 is a power steering pressure line hose assembly made for the 1978 Ford F-250. It is precision engineered to match the original routing and connection points for the listed application, helping maintain proper steering system pressure and fluid transfer. The hose uses high-grade steel tubing with zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. This part cross-references Edelmann 91582 for the same application.

Common Steering Issues This Hose Can Address

• Pressure line leaks caused by worn or damaged hose construction
• Loss of steering assist from fluid loss in the pressure circuit
• Noise or erratic steering response related to restricted hydraulic flow
• Corrosion-related hose deterioration on older Ford F-250 steering systems
• Fitment problems from an incorrect replacement pressure hose

Installation Notes and Tips

Verify the end fittings before installation: 1/2 in. male inverted flare on one end and 5/8 in. swivel O-ring on the other. Confirm hose length and routing against the original line on the 1978 Ford F-250 before tightening connections. Inspect mating surfaces, flush contaminated fluid if needed, and check for leaks after installation.

Quality Assurance

Each hose is pressure tested at the factory before shipment to help ensure proper operation and installation on the specified vehicle. The pressure rating, burst strength, and corrosion-resistant construction support long-term service in demanding steering applications.
