Detailed Product Overview

Sunsong 3402803 is a power steering pressure line hose assembly made for classic Ford Mustang steering systems that use a Ford PS pump. It is precision engineered to match the original routing and connection points, helping maintain proper hydraulic pressure between the pump and steering gear. This part cross-references Gates (e.g., 1280, 361370) for the same application.

The hose assembly uses CSM hose material and steel tubing with a zinc coating to help resist rust and corrosion from humidity, road salt, water, and grime. With a maximum working pressure of 1,500 psi, burst pressure rating of 8,700 psi, and tensile strength of 1,600 lb, this pressure line is built for demanding steering system service. Search terms such as 1965 Ford Mustang power steering pressure hose, 1966 Ford Mustang steering pressure line, and Sunsong 3402803 replacement hose all point to this application.

Common Problems This Part Addresses

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged hose
• Corrosion on the original steel line
• Cracked or worn hose material from age and heat
• Poor steering response caused by pressure loss

Installation Notes and Quality Control

Verify end sizes and routing before installation: 3/8 in. female on one end and 1/4 in. male inverted flare on the other. The 43.1 in. length is specific to the listed Ford Mustang fitment, so matching the original hose path is important for proper clearance and operation. Sunsong subjects each hose to a high-pressure quality assurance test before it leaves the factory to confirm leak-free performance and installation readiness.

Compatible With 1965-1966 Ford Mustang, N/A, with Ford PS Pump. Part number 3402803 is a direct-fit pressure line hose assembly for this classic steering application.

Quality Assurance

Every Sunsong 3402803 hose is pressure tested at the factory before shipment. The assembly is built to exceed original equipment performance standards for pressure capacity and durability, with corrosion-resistant steel tubing to support long service life in demanding driving conditions.
