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 2200 bar (≈32,000 PSI) with an M14x1.5 thread for a direct-fit replacement where that specification is required. The valve protects the high-pressure fuel rail and injectors by releasing excess pressure at its setpoint, useful in tuned or factory configurations.
