Detailed Description

Sunsong 3403453 is a power steering return line hose assembly for vehicles such as the 1975-1979 Buick Regal, 1977-1979 Ford E-150 Econoline Club Wagon, and 1977-1979 Pontiac Firebird. It is built to replace worn return hoses on classic steering systems while maintaining the correct routing, connection style, and durability expected for OE-style service.

Installation Notes and Tips

Verify end sizes, flare style, and routing before installation. This assembly uses a 3/8 in. ID hose end and a 3/8 in. male inverted flare end, so matching the original connection points is important for proper sealing. On applications with adjustable-length routing, confirm the hose path clears moving suspension and steering components and follows the original line layout.

Quality Assurance

This Sunsong steering hose assembly is manufactured to exceed original equipment performance standards for return-side service. The steel tubing is zinc electroplated for added resistance to corrosion and rust, supporting long-term durability in harsh underbody conditions.
