Detailed Description

This Sunsong pressure hose assembly is made for steering systems that require a direct-fit replacement on 1978 Ford F-150 and 1979 Ford F-150 models, including 1979 trucks built to 4/30. The hose uses a 1/2 inch male inverted flare connection on one end and a 5/8 inch swivel O-ring connection on the other, with a 30 inch length to match the original routing requirements. Sunsong 3401946 is built with CSM hose material and steel tubing, then zinc coated to improve resistance to road salt, moisture, grime, and corrosion.

For buyers searching for a 1978 Ford F-150 power steering pressure hose or a 1979 Ford F-150 steering hose replacement, this assembly is engineered to restore proper hydraulic flow in the pressure line. This part cross-references Gates 354430 for the same application.

Common Issues This Part Can Address

  • Leaking power steering pressure line hose
  • Cracked or hardened hose material
  • Loss of steering assist from pressure-side fluid loss
  • Corrosion on steel tubing or fittings
  • Improper fit from a worn or damaged original hose

Installation Notes and Tips

Verify end fitting type, hose length, and routing before installation on your Ford F-150. Inspect mating flare and O-ring surfaces, clean connection points, and confirm that the hose follows the original path without twist or contact with hot or moving components. Replace any damaged sealing surfaces or related steering components as needed during service.

Quality Assurance

Each Sunsong hose is pressure tested before it leaves the factory to help ensure consistent operation and straightforward installation. The hose construction is engineered to exceed original equipment performance standards for pressure, burst strength, and tensile durability.
