The fuel pressure relief valve - also known as the fuel pressure regulator on a common rail diesel engine - can become a weak link on a performance-tuned Duramax or Cummins.

The valve dissipates fuel pressure to prevent overloading the fuel system. After some time, the valve weakens and may drop fuel pressure when it's not needed and cause a host of problems. A weak valve can trigger engine codes P0087 or P1093. It may also be responsible for excessive smoke, poor driveability, poor mileage and a loss of power.

In this video, Duramaxtuner's Scott Henricks and Nick Priegnitz talk about the benefits of the aftermarket replacement valve. The cost is minimal compared to what a faulty valve can do to the performance and driveability of your diesel vehicle.
