Wild Diesel Race Plug - Fuel Pressure Relief Valve LB7 WD305
- Duramax 2001-2004 LB7
- It is very common for the oem pressure relief valve to fail and to relieve precious fuel rail pressure prematurely.
- When you begin to tune, program, and increase fuel in the rail it demands more from your pressure relief valve.
- This Wild Diesel billet design will make sure that you are getting all the fuel needed from your Injection Pump to your Injectors.
