GM Fuel Injector Return Line 55515929

The GM Fuel Injector Return Line 55515929 for your GM 3.0L Duramax LM2/LZ0 is a direct replacement for your factory return line. The Fuel Injector Return Line is an essential part of a diesel common-rail fuel system. While most people think about high-pressure delivery to the injectors, every injector also produces excess fuel that must be routed back to the tank or fuel system. This line is a genuine GM part that will install right into place of the old part.
