Pressure Relief Valve Shim Kit
2004.5-2010 6.6L GM Duramax
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.
