Ford HC3Z-9A564-A Fuel Injector Return Line

The Ford HC3Z-9A564-A Fuel Injector Return Line is an OEM replacement return hose designed for the fuel system on your Ford 6.7L Powerstroke. This line routes excess fuel back to the tank from the injectors, helping maintain proper fuel pressure and preventing fuel from pooling in the cylinder head area. A worn, cracked, or leaking return line can lead to poor fuel delivery, reduced performance, and fuel odors in the engine bay.

Manufactured to original equipment specifications, this return line provides proper fitment and reliable sealing with factory fuel system connections. Installing a new return line helps restore correct fuel flow and supports the overall operation of your injection system, making it an ideal service part during injector replacement or fuel system maintenance.
