Engineered specifically for 2007.5 through 2018 Dodge Ram 2500, 3500, 4500, and 5500 trucks powered by the 6.6L/6.7L ISB Cummins inline-six engine (and cross-compatible with 2004.5–2010 GM Duramax LLY, LBZ, and LMM platforms), the Bosch Original Equipment Fuel Rail Pressure Relief Valve (Part # 1110010013 / Cummins # 4938005) mounts directly to the fuel rail to safely vent excess high-pressure fuel.

Over time, constant pressure cycles weaken the internal factory spring, causing it to unseat prematurely and bleed off critical rail pressure back to the tank. This defect triggers common diagnostic codes such as P0087 and P1011, resulting in hard starting, loss of engine power, and increased exhaust smoke. Replacing a fatigued valve with a brand-new, authentic Bosch OE component guarantees factory-spec pressure control with zero core charge.

Key Features & Benefits

• Genuine Bosch Original Equipment: Manufactured by the primary OE diesel fuel system designer to ensure exact factory performance and emissions compliance.
• Cures Low Rail Pressure Codes: Resolves troublesome low pressure diagnostic codes (P0087, P1011) and unprovoked limp-mode events.
• Restores Power & Clean Combustion: Maintains proper fuel delivery pressure to the injectors, eliminating warm/cold hard starts and heavy exhaust smoke.
• High-Precision Spring Calibration: Factory-calibrated relief threshold protects sensitive common-rail components from over-pressurization spikes.
• Zero Core Charge: Brand-new outright OE component requiring no core deposit or core return shipping.

• Installation Tip: Clean the fuel rail fitting area thoroughly before removing the old valve to prevent microscopic dirt from entering the high-pressure common rail. Install the new Bosch 1110010013 valve with clean diesel fuel on the threads and torque precisely to factory specifications. (Note: For heavy-duty modified or tuned competition trucks requiring unlimited rail pressure without relief, consider pairing with a solid rail plug like BD 1050071 or PPE 113073000).
