Engineered specifically for 2004.5 through 2010 Chevrolet Silverado and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LLY, LBZ, and LMM codes), the PPE Race Fuel Valve (Part # 113073000) permanently replaces the weak spring-loaded factory pressure relief valve. Under high-performance tuning, aggressive towing, or wide-open throttle, weak factory PRV springs fatigue and unseat prematurely, dumping high-pressure fuel back to the tank and triggering P0087 or P1093 low rail pressure diagnostic codes.

The PPE race fuel valve completely blocks off the return port to lock in maximum rail pressure during peak engine load. Precision-machined from heat-treated stainless steel and 50-state emissions legal, this direct-fit upgrade ensures consistent fuel delivery straight to your injectors with zero core charge.

Key Features & Benefits

• Maintains Peak Rail Pressure: Completely blocks off the pressure relief port to prevent fuel bleeding back to the tank under full throttle.
• Eliminates Low-Pressure Codes: Cures troublesome P0087 and P1093 low rail pressure diagnostic trouble codes (DTCs) caused by weak factory springs.
• Heat-Treated Stainless Steel: Precision-machined from robust stainless steel barstock to handle extreme common-rail pressures reliably.
• 50-State Emissions Legal: CARB compliant and legal for use across all 50 states for worry-free operation.
• Zero Core Charge: Brand-new outright performance upgrade requiring no core deposit or core return shipping.

• Installation Tip: Relieve all high-pressure fuel system residual pressure completely before unthreading the factory relief valve. Clean the fuel rail mounting threads meticulously to prevent dirt from entering the common rail. Install the PPE 113073000 valve with a new Viton O-ring and torque securely to factory specifications.
