Unleash The Power Your Cummins Deserves Without Pressure Drop

If you're looking to get every ounce of power out of your 6.7L Cummins, there’s one small but critical upgrade you don’t want to overlook, the fuel rail plug. The BD Diesel Common Rail Fuel Plug is designed to replace your factory relief valve, which tends to become a weak point once you start tuning or pushing your truck harder. This high-quality plug holds rail pressure up to 30,000 PSI, giving your fuel system the ability to perform without losing pressure where it counts. That means stronger starts, more consistent throttle response, and better support for high-performance mods like tuning, larger injectors, or bigger turbos. Whether you're building a tow rig, a street monster, or something in between, sealing up your fuel rail helps deliver smoother, stronger performance under load. The installation is simple, but the payoff is noticeable every time you put your foot down. It’s a small investment that unlocks a big improvement in overall drivability and engine responsiveness.

Built To Withstand High Pressure And High Demand Conditions

The BD Diesel 1050071 Common Fuel Rail Plug is engineered to eliminate the failure-prone pressure relief valve found in 2007.5–2018 6.7L Cummins engines. Under performance tuning or heavy load, the stock valve can bleed off fuel pressure prematurely, causing hard starts, poor throttle response, and inconsistent injector output. BD’s fuel rail plug corrects this by maintaining a sealed fuel rail at pressures up to 30,000 PSI, ensuring that the injection system gets the fuel it needs without compromise. Machined for a perfect fit, the plug installs directly in place of the factory relief valve with no modifications required. It’s a must-have for trucks running increased horsepower levels or demanding towing applications where fuel delivery consistency is essential. By locking in the pressure at the rail, this upgrade helps prevent power dips and ensures optimal injector spray patterns under all operating conditions. It’s a durable, high-performance solution made for Cummins owners who expect more from their trucks.
