Brand new genuine Bosch stock CP3. Requires $200 additional core deposit refunded when old unit is returned.

It is my recommendation as well as S&S recommendation that you stick with the new CP3 pumps as they are a much higher quality than any reman. There are a lot of low priced reman CP3 pumps on the market, but I would not trust them.

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.

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.
