Detailed Description

Sunsong 3401907 is a power steering pressure line hose assembly for select 1973-1977 Ford truck applications, including F-100, F-150, F-250, and F-350 models. It is built to restore the pressure side of the steering system with exact-fit routing and the correct end fittings for the listed vehicles. The steel tubing is zinc electroplated to help resist rust and corrosion from humidity, road salt, water, and grime, while the hose construction is rated for demanding steering system pressure.

This part cross-references Gates 24030 and 364230 for the same application. The 3401907 part number is also useful when verifying replacement hose selection against OE-style references for Ford F-100, Ford F-150, Ford F-250, and Ford F-350 trucks.

Common Problems This Hose Can Address

• Leaking or cracked power steering pressure line
• Loss of steering assist from pressure-side fluid loss
• Corrosion on original steel hose tubing
• Incorrect fitment from a previous replacement hose
• Noise or inconsistent steering response caused by a worn pressure hose

Installation Notes and Tips

Verify the end fittings, hose length, and routing against the removed hose before installation. This assembly uses a 5/8 in. female end and a 1/2 in. male inverted flare end, so matching the connection style is important for proper sealing. Inspect nearby brackets, grommets, and heat shielding points during service so the replacement hose follows the original path and clears moving or hot components.

Quality Assurance

Each Sunsong pressure hose is pressure tested before it leaves the factory. The hose assembly is engineered to exceed original equipment performance standards with a 1,500 psi max working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength for dependable operation in the steering system.
