The Exergy XRG pressure relief valve is a fuel-system relief component for early 2003–2004 Dodge Cummins 5.9L applications. Rated to 2400 bar (≈34,800 PSI) and noted with a race designation, it uses an M14x1.5 thread for proper fitment. This high-pressure valve opens at its rated threshold to safeguard the fuel rail and injectors during elevated boost or high-demand conditions in race-oriented or heavily modified diesel setups.
