Are you in need of a factory replacement CP3 pump? Did you try a "parts kit" on your original pump with no fix? From stock up to 650+HP this Sportsman CP3 pumps are the best and most affordable solution for an upgraded pump that won't require significant supporting modifications or tuning.
Exergy Sportsman pumps have the following improvements over a stock pump making them a great replacement option: Higher flowing valves that last longer than stock, DLC coated plungers that are less likely to score/seize, More surface area to carry pumping loads. They also continue to increase flow with RPM beyond 3,000 RPM. Stock pumps typically stop increasing flow when RPM exceeds approximately 3,000 RPM.
Note: The Sportsman CP3 pumps intended for LB7 engines are an LBZ based pump with an LLY fuel pressure regulator for ease of tuning. Please note, these should only be used on LLY applications. Though a lift pump is not required, to achieve maximum pump performance a fuel supply of 150 GPH @ 8-10 psi per pump is recommended.
This pump can be used as a direct replacement for Bosch part numbers 0 445 020 030 and 0 986 437 308, as well as GM part number 97303762.
