Install Notes
- Tuning required to properly command rail pressure and fueling on a 14mm stroker.
- Competition/off-road use where applicable. Verify local regulations.
- Use a robust supply system; this Race Series pump uses a dedicated supply line and the OE supply port is blocked by design. Ensure ample volume and positive pressure from the lift pump.
- Thoroughly prime/bleed the fuel system after installation; maintain excellent filtration—contamination is the #1 cause of CP3 failure.
Frequently Asked Questions
Q: Is this pump suitable for a stock or lightly modified truck?
A: No—this is the Race Series 14mm unit intended for high-output builds with tuning and supporting mods.
Q: Do I need a lift pump, and how much supply does it need?
A: Yes, a high-flow lift pump is mandatory. Provide strong, steady supply pressure and volume to protect the CP3 and sustain rail pressure under load.
Q: Which injectors pair best?
A: Match injector size to your goals. 45–100% over works for aggressive street/strip; 200–300% over is typically reserved for race builds. See the Exergy LBZ options above.
Q: Is there a core charge?
A: Some CP3s carry a refundable core. If applicable, details will appear in product options or at checkout.
Q: What about warranty?
A: Covered under Exergy’s manufacturer warranty. Keep proof of purchase and follow correct install/filtration practices.
