This assembly carries fluid on the low-pressure return side of the power steering system, routing it back toward the pump reservoir. Sunsong develops and builds its own automotive fluid transfer hoses and lines. It designs them around what installers need, with the aim of delivering exact form, fit, and function.
- Rated for return duty: Exceeds original equipment performance standards, with a maximum working pressure of 250 psi. It is suited to low-pressure, high-temperature operation.
- Precision-engineered assembly: Built for exact fit and supplied with the additional components Sunsong specifies as necessary. These are intended to bring the wearable parts back to original condition.
- Corrosion-resistant tubing: The tubing resists rust and corrosion from high humidity, road salt, water, and grime.
- Pressure tested: Every return hose goes through a high-pressure quality assurance test before it leaves the factory.
Signs a return hose may need replacing include fluid seeping or dripping from the hose or its connections, a fluid level that keeps dropping, and cracked or swollen hose sections. Confirm the source of any leak before replacing parts.
