Product description

Prevent high pressure fuel problems! 

The stock 6.6L Duramax Fuel Pressure Relief Valve (FPRV) is subject to spring fatigue and eventually might not maintain stock fuel rail pressures. Additionally, anything added to your engine that increases fuel rail pressure will accelerate FPRV spring fatigue causing fuel pressure drops, and you can get Diagnostic Trouble Codes (DTC).

  • Highly recommended for modified engines
  • Machined in the USA from 304 Stainless Steel

Fits Duramax 6.6L Diesel Engines (LLY, LMM, and LBZ) years 2004.5 to 2010

Note:  Reuse original o-ring from stock plug.
