Genuine Bosch fuel pressure regulator for Duramax LMM

This is the safety relief valve in the fuel rail that can leak and cause loss of rail pressure. It is a new part that has been shimmed to increase relief pressure. If you are in need of this product do yourself a favor and add a lift pump as well.

This is a standard displacement CP3 that is modified for improved flow at speeds in excess of 3500 RPM. All are LBZ based pumps/regulators so to use in a LLY or LB7 would require custom programming of the pump flow curve.
