Product Description
More rail pressure. More headroom. More reliability. The Industrial Injection 0986437334SHO is a Bosch-based, remanufactured CP3 pump that flows ~33% over stock for the 2007.5-2018 Ram 2500/3500 6.7L Cummins. It's assembled with new OEM-grade internals and a new FCA/MPROP, then calibrated and tested for clean idle and stable commanded pressure-ideal for towing, street performance, compounds, and moderate injector upgrades.
Fitment
- 2007.5-2018 Ram 2500/3500, 6.7L Cummins (pickup)
- Direct CP3 replacement (not a CP4 conversion). Verify by VIN/engine tag before ordering.
Why upgrade to a 33% CP3?
- 33% Over Stock Flow supports higher commanded rail pressure under load for better atomization and headroom with mild injector/turbo upgrades.
- Built Right: Reman pump with new OEM-grade internal components and new metering valve (FCA/MPROP); calibrated and tested.
- Daily-driveable: Maintains smooth idle and factory-like drivability when paired with proper filtration and a quality lift pump.

FAQ
Do I need tuning for a 33% over CP3?Most towing/street builds running stock or mild injectors can maintain factory-like drivability without special tuning. For larger injectors/turbos, a proper calibration is recommended to optimize commanded rail pressure and timing. Industrial Injection lists this pump as a performance CP3 supporting higher HP targets.
What horsepower range does this support?Industrial Injection's performance CP3 lineup indicates ~33% over supports roughly the 600 HP neighborhood when the rest of the system is sized appropriately (airflow, injectors, lift pump). For 850-1050+ HP builds, step up to 10mm/12mm stroker or add a dual CP3 kit.
Is this pump 50-state legal?Performance fuel-system parts may not be legal for highway use in all areas (e.g., California). Check local regulations before purchase/installation.
What should I replace during installation?We strongly recommend fresh filtration, inspecting the FCA/MPROP, ensuring healthy return flow, and verifying HP lines/rail hardware. See the Fuel System & Components and CP3 Pumps & Components sections for compatible parts.
How does this compare to an S&S OE-grade CP3?S&S focuses on OE-grade stability and conversion options; Industrial Injection offers staged performance pumps (33%, 10mm, 12mm). Choose based on power goals and use case. For background on S&S CP3 fitment philosophies (2003-2018), see our S&S CP3 listing.
