Remanufactured Bosch CP3 high pressure fuel injection pump, part number 0 986 437 303, for the 2001-2004 GM 6.6L Duramax LB7. The CP3 generates the rail pressure the common rail injection system depends on, and a failing pump shows up as low rail pressure codes, hard starting, and pressure that falls off under load. Remanufactured by an original equipment supplier and fit, form, and function tested.
