Detailed Description

This Sunsong power steering return line hose assembly, part number 3404176, is built to restore the return side of the steering system on select Dodge trucks. It uses a 3/8 in. ID hose end on one side and a 16 mm male O-ring fitting on the other, with an overall length of 23.25 in. The steel tube construction is zinc plated to help resist road salt, water, grime, and humidity, while the hose section is suited to the heat and pressure conditions found in power steering return service. This part cross-references Dorman - HELP 80429 and Gates 1160 for the same application.

What It Helps Fix

• Power steering fluid leaks from a worn return hose
• Cracked, hardened, or heat-damaged hose material
• Corrosion on the original steel line
• Poor steering system fluid return caused by restricted or deteriorated hose routing
• Fitment issues when replacing the original hose on a 1991-1993 Dodge D250 or D350

Installation Notes and Tips

Verify the end fittings, hose length, and routing before installation. This assembly is intended for the return side of the power steering system, not the high-pressure feed line. Inspect nearby brackets, grommets, heat shields, bushings, and protective sleeves during service and replace worn components as needed to restore original routing and protection.

Quality Assurance

Sunsong states that this return hose assembly is manufactured to exceed original equipment performance standards for return-line service. The steel tubing is electroplated with zinc for improved resistance to corrosion and rust, supporting long-term durability in harsh underbody conditions.
