Sunsong 3403020 Power Steering Cylinder Line Hose Assembly - Left Turn

Power Steering Cylinder Line Hose Assembly

Sunsong 3403020 is a power steering cylinder line hose assembly built for direct replacement on select Ford trucks. It is engineered for the left turn circuit and is made to restore steering system function on 1973-1977 Ford F-250, 1976-1977 Ford F-150, and 1976 Ford F-100 applications.

Key Features

• Part number 3403020 for accurate ordering and catalog matching
• Fits left turn steering applications on select Ford F-100, F-150, and F-250 models
• 70 in. overall length for the listed vehicle applications
• 5/16 in. female end and 5/16 in. male inverted flare end
• CSM hose material with steel tubing sections for durability
• Pressure-rated construction with a 1,500 psi max working pressure and 8,700 psi burst pressure
• Electroplated zinc-coated steel helps resist corrosion from humidity, road salt, water, and grime

Detailed Description

This Sunsong power steering cylinder line hose assembly is built to meet the demands of steering systems that rely on precise hydraulic pressure. The hose uses high-grade steel tubing with a zinc coating for added resistance to rust and corrosion, while the CSM hose sections support long service life in harsh underhood and road conditions. Sunsong 3403020 is precision engineered for exact fitment and is subjected to high-pressure testing before it leaves the factory.

For fitment-based searches, this part is a direct replacement for 1976-1977 Ford F-150, left turn; 1973-1977 Ford F-250, left turn; and 1976 Ford F-100, left turn. This part cross-references Edelmann 91576 and Gates 367770 for the same application.

What It Helps Restore

• Steering fluid leaks at the cylinder line hose
• Loss of hydraulic pressure in the power steering circuit
• Corrosion-damaged or fatigued steering hose assemblies
• Steering noise or inconsistent assist caused by worn hose components
• Fitment issues from incorrect hose length or end configuration

Installation Notes and Tips

Verify the vehicle year, model, and left turn application before installation. Confirm the 5/16 in. female and 5/16 in. male inverted flare ends match the existing steering connections, and inspect adjacent steering components for wear or contamination before completing the repair. Because this assembly is engineered to exact fit, proper routing and secure connection points are important for reliable operation.

Quality Assurance

Sunsong subjects each hose to high-pressure quality testing before shipment. The assembly is built to exceed original equipment performance standards with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength.
