Fleece Performance High Fuel Injection Pump Cummins

Fleece Performance high-pressure fuel injection pumps for Cummins diesel engines are built to remove the factory fuel flow restriction in the stock CP3 injection pump. A stock CP3 loses fuel flow and rail pressure above roughly 3,000 RPM, and that loss costs power when you need it most. These upgraded CP3 pumps, also called common rail injection pumps or high-pressure fuel pumps, help the engine hold its desired fuel rail pressure through the whole RPM range.

Key Features:

• Built from brand new Bosch CP3 pumps, with no used parts and no core charge or core to return
• Designed to eliminate the factory fuel flow restriction that begins at 3,000 RPM
• Helps maintain rail pressure and fuel delivery under load
• Every pump is tested on Fleece's in-house engine simulator and pump test stand before it ships
• Product line options range from the CP3K upgrade to higher-output stroker PowerFlo pumps for more demanding builds
• Backed by a 1 year limited parts warranty
