Exergy E07 00018 Race-Only Pressure Relief Valve 2600 Bar 37700 PSI

The Exergy E07 00018 is a high-performance pressure relief valve (PRV) engineered for extreme diesel applications on Cummins 6.7L and GM Duramax LLY/LBZ/LMM platforms. Calibrated to approximately 2600 bar (37,700 PSI), this race-only component is designed to maintain commanded rail pressure under heavy load conditions where stock relief valves fall short.

Key Features:

• 2600 bar (37,700 PSI) opening pressure threshold for extreme performance builds
• Prevents premature rail pressure bleed-off in high-demand applications
• Direct replacement for factory rail PRV with OE line routing compatibility
• Precision-calibrated for consistent high-pressure fuel system performance
• Torque specification: 80 ft-lbs

Application:

• Cummins 6.7L: 2007.5-2018+ Ram applications with common-rail fuel systems
• GM Duramax: LLY (2004.5-2005), LBZ (2006-2007), LMM (2007.5-2010)

Installation Notes:

• Relieve fuel system pressure completely before removal
• Keep all fittings and ports meticulously clean during installation
• Prime and bleed fuel system after installation; verify no leaks
• Monitor commanded versus actual rail pressure after installation
• Custom tuning and healthy supply-side fuel pressure strongly recommended
