It is installed in the fuel system of heavy-duty diesel engines to allow fuel to flow in only one direction, preventing drain-back that can cause hard starting and maintaining consistent supply pressure while the engine runs. You typically replace it when you experience fuel pressure loss, backflow issues after shutdown, or as part of a fuel system overhaul on Detroit Diesel Series 60 14L and other compatible engines.
