The Exergy XRG pressure relief valve is a fuel-system relief component for early 2003–2004 Dodge Cummins 5.9L applications. It’s rated to 2000 bar (≈29,000 PSI) and uses an M14x1.5 thread for a direct-fit replacement where that specification is required. The valve prevents excessive rail pressure by opening at its rated setpoint, helping protect injectors and high-pressure fuel components in stock or modified diesel systems.
