6.6L CP3 Pump Duramax

The Modified CP3 pump Duramax flows 42% more fuel than a stock pump and adds 100 HP+ depending on how the truck is set up. The Modified CP3 injection pump was created to keep up with the demands of aggressive fueling chips and large injectors.

The CP3 pump is a high-pressure fuel pump that is used in many diesel engines, including the Duramax. The Duramax CP3 pump is responsible for pressurizing the fuel so that it can be injected into the engine. The pump is located in the fuel tank and is driven by the engine’s crankshaft. The CP3 pump has a number of moving parts, including a plunger, valves, and springs. These parts work together to create the high pressure needed to inject the fuel into the engine. Over time, these moving parts can wear out, causing the Duramax CP3 pump to fail.

When this happens, the engine will not run properly and may even stall. Contact DFC as we provide the highest quality Duramax CP3 pump possible.
