CP4 Injection Pumps

Browse new and remanufactured CP4 high-pressure fuel pump listings for pickup and industrial diesel repairs. Bosch application examples include Ford 6.7L Power Stroke and GM Duramax LML and LGH engines, with separate pump numbers identified in the maker’s guides. The page also lists industrial applications that require their own number check. Record the full number on the original pump, engine details and VIN or engine serial number. Review the selected listing’s replacement references and assembly contents before ordering. If the repair follows a contaminated fuel system, discuss that history too and call 530-668-0818 to confirm the fit.

Common questions

Does a later model year automatically mean my truck uses a CP4?
No. Identify the engine and original pump number, then check the specific application rather than relying on ‘2011 and later’.

What information should I have ready for a fit check?
The original pump number, engine version, VIN or engine serial, and whether the job involves fuel contamination.
