Detailed Description

This Sunsong power steering return line hose assembly, part number 3402098, is built for vehicles that route fluid from the cooler back to the reservoir. It is a direct replacement for 1990-1994 Chevrolet Lumina, 1991-1993 Buick Regal, 1991-1993 Oldsmobile Cutlass, 1991-1993 Oldsmobile Cutlass Supreme, and 1991-1993 Pontiac Grand Prix applications, including the 1991 Buick Regal from VIN #80001. The hose is designed for low-pressure return use and high-temperature operation, with steel tubing protected by zinc plating to help resist corrosion from humidity, road salt, water, and grime.

This part cross-references Dorman - HELP 92203 and Gates 365586 for the same application.
