What does a power steering pressure hose do?
It carries high-pressure fluid from the power steering pump to the steering gear. That fluid supplies the hydraulic assist that helps reduce steering effort.

Sunsong rates it at a 1,500 psi max working pressure, an 8,700 psi burst pressure, and 1,600 lb. of tensile strength.
How do I know if my pressure hose is failing?
Possible signs include fluid leaks at the hose or fittings, a fluid level that keeps dropping, pump whine, or stiffer steering. Diagnose the cause first, because other components can produce the same symptoms.
Is the hose tested before it ships?
Yes. Every Sunsong pressure hose goes through a high-pressure quality assurance test before it leaves the factory.
