Detailed Description

Sunsong 3401903 is a power steering pressure line hose assembly made for Dodge B-Series vans in the 1992-1993 model years. It is a direct-fit replacement for the pressure side of the steering system and is built to match the original routing and connection style used on the listed vehicles. This part cross-references Gates 1310 for the same application.

The hose assembly uses CSM and steel construction, with male O-ring fittings at both ends for secure connection. The steel tubing is electroplated with zinc to improve resistance to rust and corrosion, which is important in vehicles exposed to moisture, road salt, and road debris. The Sunsong 3401903 pressure line is also pressure-tested before it leaves the factory to help support consistent installation and operation.

Common Problems This Part Can Help Solve

• Power steering fluid leaks from a worn or damaged pressure hose
• Loss of steering assist caused by pressure line failure
• Cracked, corroded, or fatigued original hose tubing
• Steering noise or erratic assist related to pressure loss
• Fitment issues when replacing the original Dodge B150, B250, or B350 pressure line

Installation Notes and Tips

Verify vehicle fitment before installation, especially on 1992-1993 Dodge B150, B250, and B350 models. This application excludes vehicles equipped with Hydroboost. Confirm both fitting sizes and the hose routing against the original line before tightening connections. Inspect surrounding steering components, seals, and fluid condition during replacement to help prevent repeat leaks.

Quality Assurance

Each Sunsong pressure hose is subjected to high-pressure testing before shipment to support trouble-free installation and operation. The hose assembly is engineered to exceed original equipment performance standards for pressure capacity and durability.
