Detailed Description

This Sunsong power steering pressure line hose assembly is built to restore hydraulic steering flow on Ford E-350 Econoline and Ford E-350 Econoline Club Wagon models. Part number 3401868 is precision engineered to match the original routing and connection points, helping maintain proper steering response and leak-resistant operation. The steel tubing is zinc coated to resist rust and corrosion from humidity, road salt, water, and grime, while the hose materials are selected for durability in demanding underhood conditions. This part cross-references Dayco 71849 for the same application.

What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by pressure hose failure
• Corrosion-related deterioration in the steering line
• Improper hose routing or fitment on replacement service
• Noise or erratic steering performance related to hydraulic pressure loss

Installation Notes and Tips

Verify end fittings before installation: 1/2 in. male inverted flare on one end and 16 mm male O-ring on the other. Confirm vehicle application for 1992 Ford E-350 Econoline and E-350 Econoline Club Wagon built from 6/1, as well as 1993-1996 Ford E-350 Econoline and E-350 Econoline Club Wagon. Inspect mating components, flush contaminated fluid if needed, and check for proper line routing and clearance after installation.
