Designed To Deliver Constant Pressure And Cleaner Fuel

The FASS DMAX7001 Flow Enhancer Fuel Pump is engineered to support the fuel demands of 2001–2010 GM 6.6L Duramax engines by delivering a steady 8 PSI to the CP3 pump. This constant pressure reduces the workload placed on the injection system, helping to improve both reliability and overall efficiency. The pump also helps prevent harmful contaminants like air, water, and fine debris from disrupting fuel flow—a key issue in vacuum-based setups. As a result, your injection system benefits from a cleaner and more stable fuel supply, promoting better atomization and combustion. This translates into improved throttle response, smoother operation, and even potential fuel mileage gains. Designed with simplicity in mind, the Flow Enhancer installs quickly using your truck’s existing layout and wiring. It’s a practical and effective solution for anyone looking to extend the life of their injection pump while improving day-to-day performance. For Duramax owners looking to improve reliability and drivability, this pump offers a balanced mix of value and function.
