The Exergy 12mm Stroker CP3 Conversion Kit swaps the factory Denso HP4 pump on a 2017 and newer L5P Duramax for an Exergy 12mm Stroker CP3. A CP3 conversion is the common route when an L5P build needs more fuel than the factory pump can supply.

Part number: E12 10707.
Power: Supports 1,000+ horsepower from a single pump, per Exergy.
Fuel supply: Exergy calls for 150 GPH at 15 psi to get full pump output.

Required: Custom tuning and supporting modifications. Call us before you order and we will go over the parts in the kit and what your build needs with it.
