Fuel Return Pipe – GM (55506065)

Fuel Return Pipe routes fluid through the engine bay or underbody. The crimp or flare is the usual failure point, and it fails from vibration rather than from pressure.

Replace the Fuel Return Pipe when a leak appears at a flare or when the line has been bent close to a heat source. Routing must follow the original path or it will chafe.

This Fuel Return Pipe is listed under part number 55506065, filed under Fuel Rails & Lines. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.
