Product Description
The BD DIESEL 1050071 Fuel Rail Plug is a must-have reliability upgrade for common rail Duramax and Cummins fuel systems. This plug replaces the factory fuel pressure relief valve that can weaken over time and begin bleeding off rail pressure—causing hard starts, reduced performance, and drivability issues. The BD Fuel Rail Plug is engineered to seal up to 30,000 PSI rail pressure to help maintain consistent fuel pressure under load, making it ideal for stock trucks and performance builds alike.
This plug installs in place of the factory relief valve with no modification required and includes a new O-ring for a complete installation. By preventing pressure loss, it helps improve engine starting, throttle response, and overall fuel system consistency.
