Frequently Asked Questions

Which CP3 pump is right for my 6.7 Cummins?

For stock trucks or towing, choose the OEM replacement CP3. For higher horsepower, an Exergy 10mm or 12mm CP3 works well. For extreme race builds, a 14mm CP3 or multi-pump setup is ideal.

Can I daily drive with a performance CP3?

Yes. Many customers run 10mm or 12mm CP3s daily with matched injectors, turbos, and proper tuning.

When should I consider dual or triple CP3s?

When a single CP3 cannot maintain desired rail pressure under load—common in very high horsepower builds—dual or triple setups provide stable fueling and protect components.

Do you bench-test CP3 pumps?

Absolutely. Every CP3 pump is flow-tested and calibrated before it leaves our facility.

Do you offer installation support?

Yes. We provide guidance for installation, break-in, and tuning to ensure your CP3 delivers optimal performance.
