Injector Return Line Cap – CH-50377
Used for diagnosis of the fuel system in the 6.6L Duramax diesel. The engine now features piezo activated injectors. The CH-50377 plugs the injector fuel line to seal it off and allow isolation of each injector so a fuel volume test can be performed and compared to the service specification standard. Each injector line is sequentially disconnected and plugged with the CH-50377. The volume check is run using the graduated cylinders in previously essential J-45873-100 Volume Test Set.
