CUMMINS CP4 Pump Catastrophic Failure Replacement Kit. When a CP3 Injection Pump fails, a "grenade effect" type of failure happens. This effect spreads debris contamination throughout the entire fuel system. No amount of flushing and cleaning will restore your system to the original operating conditions.
