Detailed Description
This Sunsong power steering pressure line hose assembly, part number 3404368, is built to restore hydraulic steering performance on Ford Super Duty trucks with hydroboost systems. It is a fitment-based replacement for pump-to-hydroboost routing on 2011-2016 Ford F-250 Super Duty and 2011-2016 Ford F-350 Super Duty, with specific 2011 and 2013-2016 Ford F-350 applications noted for hydroboost-equipped vehicles. The hose uses a male O-ring fitting on one end and a swivel O-ring fitting on the other, helping match the original connection points for a proper service replacement.
According to the manufacturer, the pressure hose construction is rated above original equipment performance standards, with a 1,500 psi maximum working pressure, 8,700 psi burst pressure, and 1,600 lb tensile strength. The steel tubing is zinc electroplated to help resist corrosion from humidity, road salt, water, and grime, which is important for trucks that see year-round use. Sunsong 3404368 is a practical choice when replacing a worn or leaking Ford F-250 Super Duty or Ford F-350 Super Duty power steering pressure line.
What It Helps Fix
- Power steering fluid leaks at the pressure line
- Loss of steering assist from a damaged hose assembly
- Cracked, corroded, or fatigued pressure tubing
- Hydroboost steering circuit pressure loss
- Noise or inconsistent steering feel caused by hose deterioration
Installation Notes and Tips
Verify the vehicle uses a hydroboost system before ordering. Confirm the end fittings, routing, and hose length against the original line on the truck, especially on 2011-2016 Ford F-250 Super Duty and 2011-2016 Ford F-350 Super Duty applications. This part number 3404368 is a pump-to-hydroboost pressure line, so it should be matched to the correct steering circuit position during service.
Quality Assurance
Each hose is pressure tested at the factory before it leaves production. Sunsong also specifies exact-fit engineering and corrosion-resistant tubing construction to support reliable operation in demanding steering applications.
