Fuel Related 2016-2022 GM 2.8L Duramax

The factory fuel system in your 2016-2022 GM Canyon or Colorado with the 2.8L Duramax diesel includes an underbed fuel tank, lift pump, high-pressure injection pump, and electronically controlled injectors. While effective, these systems have their limitations, particularly with the stock lift pump, which can become a weak point. The factory setup relies on the injection pump to "pull" fuel from the tank under vacuum, rather than using a dedicated lift pump to "push" fuel. This creates additional strain on the system, increasing the risk of cavitation and introducing air into the fuel — common causes of injector and pump failure. The result is reduced reliability and performance, especially if you’ve added a tuner or other performance modifications. To address these issues, we recommend upgrading to a high-pressure fuel system from trusted brands like FASS or Pureflow. These advanced systems significantly improve reliability and performance by incorporating superior filtration and air separation. By removing particulates, water, and air, they protect your fuel system from cavitation and extend the life of your injectors and pump. For those pushing their 2.8L Duramax to higher performance levels, we also offer upgraded injectors and injection pumps designed to handle increased fueling demands. These upgrades ensure consistent fuel delivery and help maximize the potential of your tuned engine.
