The ATS Diesel fuel rail pressure plug for 2004.5-and-up GM trucks provides a factory-style closure for the fuel rail pressure port during service or fuel-system modifications. Installing the plug seals the port to help prevent leaks and allows technicians to work on the rail or fuel lines without removing adjacent components, simplifying routine service and repairs on compatible GM truck fuel rails.
