Detailed Description

This Sunsong power steering pressure line hose assembly, part number 3402339, is engineered for direct replacement on 2005-2010 Ford Mustang models. The hose is precision built to restore the original routing and connection points, including the bracket and pressure switch port required by the application. Sunsong 3402339 is designed with a male captive O-ring end on one side and a swivel O-ring end on the other for proper steering-system connection and sealing.

For durability, the assembly uses CSM hose material and steel tubing with a zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. The pressure hose is rated beyond typical OE performance targets, with a 1,500 psi maximum working pressure, 8,700 psi burst pressure, and 1,600 lb tensile strength. This makes it a practical replacement choice for Mustang owners addressing steering fluid leaks or pressure-line wear.

What It Helps Fix

• Power steering fluid leaks at the pressure line
• Steering assist loss caused by hose damage or internal wear
• Corrosion-related line deterioration on the Ford Mustang
• Improper fitment from a bent, fatigued, or previously repaired hose
• Warning light or drivability concerns related to the pressure switch port connection

Installation Notes and Tips

Verify end sizes, routing, and bracket locations before installation. This hose assembly is built for 2005-2010 Ford Mustang applications, so confirm the vehicle year and steering connection style match part number 3402339. Inspect mating seals, fittings, and surrounding steering components for wear before reassembly to help prevent repeat leaks.

Quality Assurance

Each Sunsong 3402339 hose is pressure tested before it leaves the factory to support reliable installation and operation. The assembly is manufactured to restore worn wearable parts to original condition and to provide consistent fit and sealing performance for the Mustang power steering system.
