Sunsong is a vertically integrated manufacturer that researches, develops and builds automotive fluid transfer hoses and lines. It designs its assemblies around what installers need and to deliver exact form, fit and function.
- Pressure ratings: Max working pressure of 1,500 psi, burst pressure rating of 8,700 psi and tensile strength of 1,600 lb. Sunsong states its pressure hoses exceed original equipment performance standards.
- Pressure tested: Every pressure hose goes through a high-pressure quality assurance test before it leaves the factory.
- Pre-assembled with brackets: Sunsong's pressure and return assemblies come pre-assembled with brackets. This allows easier installation and reduced labor time compared with replacements sold as individual hoses.
- Precision engineered: Built by Sunsong to an exact fit for the listed applications.
Signs this hose may need replacing include power steering fluid leaking at the line or its fittings, a steadily dropping fluid level, pump whine, or heavier steering effort. If a leaking or damaged pressure line is the cause, this assembly replaces it. Diagnose the system before replacing parts.
