Product Description

Industrial Injection 23F401 Triple CP3 Kit — Fits 2003–2018 Ram 2500/3500 5.9L & 6.7L Cummins

Push past rail pressure drop and fuel your big-power Cummins build. The Industrial Injection Triple CP3 “kit only” adds bracketry and pulleys to run three CP3 pumps for the fuel volume demanded by high-boost, competition setups. The oversized 10" billet CP3 pulleys slow pump RPM for better efficiency and pump life at high engine speed.

FAQ

Does this include CP3 pumps, belt, or fuel lines?

No. This is a hardware kit only. You will add your chosen CP3 pumps, belt length, and fuel plumbing.

How do the 10" pulleys help at high RPM?

The larger pulley diameter slows pump RPM relative to engine speed, improving volumetric efficiency and reducing pump wear in high-RPM, high-rail-pressure use.

What power level is this aimed at?

Typically 1500+ HP competition builds where dual CP3 systems start to run out of supply.

Is custom tuning required?

Yes — any triple-pump setup should be paired with appropriate fueling/tuning and injector/air upgrades.
