Detailed Description

Sunsong 3402741 is a power steering pressure line hose assembly made for the pump-to-hydroboost circuit on 2003 Dodge Ram 1500, Ram 2500, and Ram 3500 trucks with hydroboost, to 8/31. It is precision engineered to match the original routing and connection points, helping maintain proper steering assist and brake booster hydraulic performance in the Ram platform. The hose assembly uses high-grade steel tubing with a zinc coating to resist humidity, road salt, water, and grime, while the CSM hose section is selected for demanding steering-system service. This part cross-references Dorman – HELP 80685 for the same application.

What This Part Helps Address

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged hose assembly
• Hydraulic pressure loss between the pump and hydroboost unit
• Corrosion-related line deterioration on Ram trucks
• Fitment issues caused by incorrect hose length or end configuration

Installation Notes and Tips

Verify the vehicle is a 2003 Dodge Ram 1500, Ram 2500, or Ram 3500 with hydroboost and the correct build cutoff before ordering. Confirm the end fittings match the application: 18 mm female O-ring on one end and 16 mm male O-ring on the other. Inspect adjacent steering components, brackets, and mounting points for wear or corrosion before installation. Sunsong 3402741 is intended for the pump to hydroboost position and should be routed to match the original line path.

Quality Assurance

Each hose assembly is subjected to high-pressure quality testing before leaving the factory. Sunsong 3402741 is built to exceed original equipment performance standards for pressure, burst resistance, and tensile strength, supporting dependable operation in the steering system.
