- Eliminates low fuel pressure rail diagnostic trouble codes (DTC) such as 1093 (low fuel pressure during power regiment)
- Maintains fuel pressure during full throttle
- Reduces the amount of fuel released back to fuel tank
Application: 2004.5-2010 Duramax LLY, LBZ and LMM diesel engines
2007.5-2011 Dodge Cummins 6.7L diesel engines
The shim kit effectively shim’s the PRV (pressure relief valve) increasing its “pop off” pressure, thus reducing fuel being returned to the tank by the PRV. The Release Valve Shim Kit eliminates low fuel pressure rail diagnostic trouble codes (DTC) such as DTC P01093 (low fuel pressure during power regiment), help maintains fuel pressure during full throttle driving. Available for 2004.5-10 Duramax Diesels (LLY/LBZ/LMM).
