Detailed Description

This Sunsong power steering pressure line hose assembly is engineered for direct replacement on 1977 and 1978 Dodge B100, Dodge B200, and Dodge B300 models, with fitment listed for w/o Air Pump configurations where noted. Part number 3401745 is built to restore steering hydraulic flow with the correct hose routing, fitting sizes, and connection types for the application. This part cross-references Dayco 71036 and Gates 366870 for the same application.

For Dodge B100, B200, and B300 steering repairs, 3401745 provides a pressure-rated hose assembly with corrosion-resistant steel tubing and a CSM hose section to handle the demands of the power steering circuit. The assembly is precision engineered to match the original layout and restore worn pressure line function on the vehicle.

What It Helps Fix

• Power steering fluid leaks from a worn or damaged pressure line
• Hard steering caused by pressure loss in the hydraulic circuit
• Noisy steering operation related to restricted or failing hose flow
• Corrosion damage on the original steel line
• Fitment issues from an incorrect replacement hose on Dodge B-series vans

Installation Notes and Tips

Verify end fitting types before installation: 5/8 in. male inverted flare on one end and 1/2 in. male O-ring on the other. Confirm the vehicle is a 1977-1978 Dodge B100, B200, or B300 and check whether the application is w/o Air Pump where required. Inspect mating seals, routing points, and adjacent steering components before final tightening.

Quality Assurance

Each hose is high-pressure tested before it leaves the factory to help ensure proper operation after installation. Sunsong states that the pressure hose assembly exceeds original equipment performance standards, with pressure and strength ratings intended for demanding steering-system service.
