Exergy Diesel Injectors and CP3 Pumps for Cummins Duramax Powerstroke

What This Exergy Collection Covers

Exergy Performance specializes in diesel injection components for high demand towing, street performance and competition builds. Product options are listed by engine family, model year and fuel system configuration.

Fuel Injectors and Injector Sets

New and remanufactured injector options are available for Cummins, Duramax and Powerstroke applications. Select flow level only after confirming supporting turbo, lift pump, tuning and engine goals.

CP3 and CP4 Injection Pumps

The collection includes stock replacement, upgraded and stroker injection pump options for common diesel platforms. Pump selection affects fuel volume, rail pressure capability and the supporting parts required for installation.

CP3 Conversion Planning

A CP3 conversion can replace a compatible factory high pressure pump configuration on selected applications. Read the kit contents and vehicle notes to confirm rails, lines, fittings and tuning requirements.

Fuel Rails, Lines and Sensors

Fuel rails, high pressure lines, metering valves, pressure sensors and relief valves support a complete diesel injection system. Match each component to the engine generation and factory or modified fuel layout.

Supporting Fuel Supply

A healthy lift pump and filtration system supports stable supply to the high pressure pump. Confirm supply pressure, filtration service and fuel quality before adding high flow injection components.

Build Matching and Service

Diesel fuel upgrades work as a system. Injector size, pump capacity, turbo airflow, tuning and drivetrain limits should be planned together for dependable results.

Fitment Before Installation

Check model year, engine code, emissions configuration and current fuel system parts. Product pages identify engine family specific hardware and installation notes.
