Detailed Description

This Sunsong power steering pressure line hose assembly, part number 3401804, is built for direct replacement in select Ford full-size van applications. It is sized for the pressure side of the steering system and uses male inverted flare fittings at both ends for the specified Ford Econoline and Econoline Club Wagon fitments. The hose assembly is manufactured with corrosion-resistant steel tubing and a protective zinc coating to help withstand humidity, road salt, water, and grime. This part cross-references Dayco 71200 and Gates 361910 for the same application.

What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Steering noise caused by pressure loss in the hydraulic system
• Hard or inconsistent steering effort from restricted fluid flow
• Corrosion-related hose deterioration on older Ford vans
• Fitment issues when replacing an original pressure line on select Econoline models

Installation Notes and Tips

Verify the end fitting sizes, hose length, and vehicle application before installation. This hose is listed without a bracket and without a power steering switch port. Confirm the routing and connection points on 1977 Ford E-100, E-150, E-250, and E-350 Econoline models from serial number 85000 and on 1978-1979 Ford E-100, E-150, E-250, and E-350 Econoline and Club Wagon models. Properly inspect related steering components and replace any worn seals or damaged lines during service.

Quality Assurance

Each hose is pressure tested before leaving the factory to help ensure proper operation after installation. Sunsong builds this pressure line to exceed original equipment performance standards for strength, pressure capacity, and corrosion resistance.
