Detailed Description

Sunsong 3402941 is a power steering pressure line hose assembly for hydroboost steering systems used on select Ford Super Duty trucks. The hose is built to meet demanding pressure requirements, with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength. High-grade steel tubing with zinc electroplating adds corrosion resistance against humidity, road salt, water, and grime.

This Ford F-250 Super Duty power steering pressure line hose and Ford F-350 Super Duty pump to hydroboost hose is precision engineered for exact fit. The design supports proper routing and connection at the pump and hydroboost unit, helping restore the steering hydraulic circuit to original operating condition. Part number 3402941 is also a useful reference when comparing replacement options for the same vehicle application.

What It Helps Fix

• Power steering fluid leaks at the pressure line
• Cracked, worn, or corroded hose sections
• Hard steering caused by pressure loss in the hydraulic circuit
• Hydroboost system performance issues tied to hose deterioration
• Noise or fluid seepage from damaged fittings or hose routing

Installation Notes

Verify hydroboost system configuration before ordering, since this hose is for pump to hydroboost routing on the listed Ford Super Duty trucks. Confirm the 16 mm male swivel O-ring end fittings and 75.8 in. overall length match the original hose layout. Inspect adjacent steering components, mounting points, and sealing surfaces before installation to help ensure proper fit and leak-free operation.

Quality Assurance

Each Sunsong hose is pressure tested before it leaves the factory. The manufacturer also specifies performance targets above original equipment standards, along with corrosion-resistant tubing construction for long service life.
