Detailed Description

Sunsong 3403009 is a power steering pressure line hose assembly for the 1958-1960 Ford Thunderbird. It is built to meet demanding pressure requirements, with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength. The steel tubing is zinc plated to help resist rust and corrosion from humidity, road salt, water, and grime, while the precision-fit design supports a clean replacement on the original steering system.

This part number 3403009 is a direct-fit pressure hose for Thunderbird owners replacing a worn, leaking, or damaged steering line. It also cross-references Gates 352065 for the same application.

Common Issues This Part Can Address

• Power steering fluid leaks from a cracked or worn pressure hose
• Steering effort that increases when the hose is restricted or damaged
• Noise caused by pressure loss in the steering hydraulic circuit
• Corrosion on the original steel line
• Fitment problems from an incorrect replacement hose

Installation Notes and Tips

Verify the end fittings, hose length, and routing against the original line before installation. This assembly uses 1/4 in. male inverted flare and 3/8 in. male inverted flare ends, with no bracket or pressure switch port. Inspect adjacent steering components, seals, and hard lines for wear before completing the repair.

Quality Assurance

Each Sunsong hose is pressure tested at the factory before it leaves production. The hose assembly is engineered to restore original-condition wear items on the steering line and to support trouble-free installation on the listed Ford Thunderbird applications.
