Sunsong is a vertically integrated manufacturer that researches, develops, and builds automotive fluid transfer hoses and lines. It designs its products around what installers actually need.

• Rated for return-side duty: Sunsong return hoses exceed original equipment performance standards. They have a maximum working pressure of 250 psi and are suited to low-pressure, high-temperature operation.
• Precision-engineered fit: Return assemblies are engineered to an exact fit and come with the additional components needed for the replacement.
• 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 this return line may need replacing include:

• power steering fluid seeping or dripping from the hose or its fittings
• a hose that is cracked, swollen, or soft
• a fluid level that keeps dropping

Low fluid can also lead to pump whine or heavier steering, so diagnose the source of any leak before replacing parts.
