2004.5–2007 5.9L Cummins Injection Pumps & Fuel Supply

The 2004.5–2007 group covers the later high-output 5.9L common-rail platform. Industrial Injection catalogs this range separately from 2003–2004 because injector, turbo and other application details change at the mid-2004 break.

This collection includes stock and performance CP3 pumps, FCA components, CP3 upgrade parts, rail-pressure components, multiple-pump systems and FASS fuel-supply products. The injection pump creates the high pressure required by the engine's injection system, while a lift or supply pump moves fuel from the tank and feeds the high-pressure side. Upgrading one does not replace the function of the other.

Use the exact model year and current injector, pump or turbo number because the 2004 mid-year break is important. For performance combinations, match pump capacity to injector size, tuning and intended power level rather than choosing a pump only by an advertised flow number.
