Exergy Model E04 10305Exergy 06-07 Chevrolet Duramax 6.6L LBZ Sportsman CP3 Pump (LBZ Based) Are you in need of a factory replacement CP3 pump? Did you try a "parts kit" on your or iginal pump with no fix? From stock up to 650+HP these 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 higher flowing valves that last longer than stock making them a great replacement option. 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: 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 0 445 020 037, 0 445 020 105, and 0 986 437 332, as well as GM part numbers 97780161, 97720662, 97361351, and 8973613516. Show more
