Product Description
Chase 1000+ HP with clean packaging and no dual-fueler clutter. The Exergy E04 20317 Reverse Rotation 12mm Stroker CP3 Pump delivers massive high-pressure fuel in a compact single-pump layout. Built by Exergy Performance, this stroker CP3 is engineered for race/off-road builds where a reverse-rotation belt/gear drive is used for secondary/standalone fueling.
Key Benefits
- 12mm stroker CP3 for significantly increased fuel volume and rail pressure stability
- Reverse-rotation pump intended for belt- or gear-driven auxiliary locations (not the OEM CP3 spot)
- Exergy-calibrated and flow-verified for repeatable performance
- Ideal for big-injector, single or compound turbo builds targeting 1000+ HP
Fitment / Use Case
- Application: Universal race/off-road. Designed for reverse rotation drives. Does not fit factory CP3 locations on Cummins or Duramax.
- Fuel Supply Requirement: Plan for a high-capacity low-pressure supply (e.g., lift pump system) capable of supporting aggressive flow demands.
- Emissions/CARB: Not CARB legal. Off-road/competition use only.
What’s Included
- Exergy E04 20317 Reverse Rotation 12mm Stroker CP3 Pump

Install Notes
- Professional installation required. Reverse-rotation drive mounting/bracketing and plumbing are builder-specific.
- Prime/bleed the low-pressure side thoroughly before startup; monitor rail pressure during initial runs.
- Use high-quality filtration and water separation; contamination is the #1 cause of HPFP failure.
Frequently Asked Questions
Q: Will this fit the stock CP3 location on my Cummins or Duramax?
A: No. This is a reverse-rotation pump intended for auxiliary/belt-drive or gear-drive locations, not the OEM CP3 spot.
Q: What fuel supply should I run?
A: Use a high-capacity lift pump system with adequate GPH and stable inlet pressure under load. See our lift pump category or FASS/AirDog brand pages.
Q: Is tuning required?
A: Yes—most builds using a 12mm stroker CP3 and large injectors will require custom calibration to manage rail pressure and fueling.
Q: Street legal?
A: This pump is not CARB legal and is intended for off-road/competition use.
