Front Fuel Return Pipe – GM (15731644)

Front Fuel Return Pipe is a formed tube, hose or pipe that moves fluid between two points. Bend radii and fitting angles are specific to the application, so a line that looks similar may not clear the surrounding components.

Replace the Fuel Return Pipe when the tube is kinked, when a fitting is stripped, or when the outer layer of a hose has cracked. Do not attempt to repair a high-pressure line with a splice.

This Fuel Return Pipe is listed as part 15731644 (Fuel Rails & Lines). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

Genuine GM supplied for this Fuel Return Pipe, with the engineering number unchanged from the factory reference stamped on the original.

The listing covers the front position of the assembly.
