Detailed Description

Sunsong 3401711 is a power steering pressure line hose assembly for 1987-1989 Ford Mustang models. It is engineered to meet original equipment performance standards with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength. The hose uses high-grade steel tubing with zinc electroplating for added resistance to corrosion from humidity, road salt, water, and grime. This part cross-references Dayco 70443 for the same application.

What It Helps Address

  • Power steering fluid leaks at the pressure line
  • Loss of steering assist from a damaged hose
  • Noise or erratic steering caused by pressure loss
  • Corrosion-related hose deterioration
  • Fitment issues from an incorrect replacement line

Installation Notes and Tips

Verify the 9/16 in. and 5/8 in. swivel O-ring connections, 43.4 in. length, and PS switch port before installation. Confirm routing against the original hose on your Ford Mustang to ensure the line follows the factory path and clears surrounding components. Part number 3401711 is intended for the listed 1987-1989 Mustang applications.

Quality Assurance

Each hose is pressure tested before it leaves the factory to confirm proper sealing and operation. Sunsong builds this pressure line to restore original-condition wear components and support trouble-free installation on the specified Ford Mustang models.
