Exergy Sportsman CP3 Conversion Kit | 2017 and Newer L5P Duramax
Part#:
Description
The Exergy Sportsman CP3 Conversion Kit swaps the factory Denso HP4 pump on a 2017 and newer L5P Duramax for an Exergy Sportsman CP3. A CP3 conversion is the common route when an L5P build needs more fuel than the factory pump can supply.
- Fits: 2017 and newer Chevy Silverado and GMC Sierra 2500HD and 3500HD with the 6.6L L5P Duramax.
- Part number: E12 10705.
- Power: Supports from stock up to 650+ horsepower, per Exergy. It is the kit for replacing a worn HP4 that is losing rail pressure.
- Fuel supply: A lift pump is not required. For full pump output Exergy recommends 150 GPH at 15 psi.
- Tested: Every pump is run to 4,500 RPM and 29,000 psi before it ships, and the pump design passed a 40 hour durability test at 4,500 RPM.
- Flows past 3,000 RPM: Higher flowing valves keep flow climbing past 3,000 RPM, where a stock pump levels off.
- Required: Custom tuning. Call us before you order and we will go over the parts in the kit and what your build needs with it.
- Core charge: None. You keep your old pump.
- Warranty: Exergy backs it for 2 years against defects in workmanship and material. It covers the original buyer in the continental US and Canada. Labor and towing are not covered.
