Power Steering Return Line for Ford E-Series

Sunsong 3404676 is a power steering return line hose assembly for Ford E-150, E-250, E-350 Super Duty, and related E-Series applications. It is built for low-pressure, high-temperature return-side service and is engineered for exact fit on the cooler-to-reservoir route.

Key Features

• Max working pressure of 250 psi for return-line operation
• High-grade steel tubing with zinc electroplating for corrosion and rust resistance
• Precision-engineered fit for the cooler to reservoir position
• Includes brackets, grommets, heat shields, bushings, and protective sleeves as required
• Fits Ford E-150, E-250, E-350 Super Duty, Econoline Van, Econoline Wagon, and related E-Series models

Detailed Description

This Sunsong power steering return line hose assembly is made to restore the return-side steering circuit on Ford E-Series vans and wagons. The 3404676 hose assembly uses steel tubing with a zinc coating to resist corrosion from humidity, road salt, water, and grime, while the hose construction is rated for low-pressure, high-temperature service. It is a direct-fit replacement for the cooler to reservoir position on applications such as the Ford E-150, E-250, and E-350 Super Duty.

This part cross-references Monroe Shocks & Struts 5763 for the same application.

What It Helps Fix

• Power steering fluid leaks in the return line
• Corrosion damage on the original steel tubing
• Heat-related hose deterioration
• Restricted or damaged cooler-to-reservoir routing
• Steering fluid loss on Ford E-Series vehicles

Installation Notes and Tips

Verify the cooler-to-reservoir routing and match the vehicle’s steering configuration before installation. Some 2011-2014 Ford Econoline Van and Econoline Wagon applications with hydroboost systems require the power steering return line end fitting noted in the fitment data. Confirm all connection points, brackets, and protective components align with the original layout before final tightening.

Quality Assurance

Sunsong states that this return hose assembly exceeds original equipment performance standards for return-line service and is precision engineered for exact fit. The part number is 3404676.
