Keep high-pressure fluid flowing to the steering gear with the Sunsong power steering pressure line hose assembly, part number 3404132. It is a direct-fit replacement for the 2007-2009 Lexus RX350. Sunsong designs it to deliver exact form, fit, and function.
The pressure line carries pressurized power steering fluid from the pump to the steering gear. Sunsong is a vertically integrated manufacturer that researches, develops, and builds automotive fluid transfer hoses and lines, and it develops its products around what installers need.
- Pressure ratings: The hose has a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and a tensile strength of 1,600 lb. Sunsong states that these figures exceed original equipment performance standards.
- Pre-assembled with brackets: Sunsong ships its pressure and return assemblies with the brackets already fitted. This is intended to make installation easier and reduce labor time compared with replacements sold as individual hoses.
- Precision engineered: Sunsong builds these assemblies to an exact fit and supplies the additional components they require.
- Pressure-tested: Each pressure hose goes through a high-pressure quality assurance test before it leaves the factory.
Signs that a pressure line may need replacing include power steering fluid leaking at the hose or its fittings, a falling fluid level, a whining pump, or heavier steering effort. Diagnose the cause before ordering. If the pressure line is the source of the problem, this assembly replaces it. See the Buyer's Guide tab for application details.
