Sunsong is a vertically integrated manufacturer that researches, develops and builds automotive fluid transfer hoses and lines. It designs its products around what installers need and aims to go beyond industry quality standards, with the goal of exact form, fit and function.
- Rated for return-side duty: Sunsong states that its return hoses exceed original equipment performance standards. They carry a maximum working pressure of 250 psi and are suited to low-pressure, high-temperature operation.
- Precision-engineered assembly: Sunsong precision-engineers its return assemblies to an exact fit.
- Corrosion- and rust-resistant tubing: The tubing is designed to stand up to high humidity, road salt, water and grime.
- Pressure tested: Each return hose goes through a high-pressure quality assurance test before it leaves the factory.
Signs a return line may need replacing include power steering fluid seeping or dripping from the hose or its connections, a reservoir level that keeps dropping, or a hose that looks cracked. If the return line is the source of the leak, this assembly replaces it. See the Buyer's Guide tab for engine details on each application.
