Industrial Injection 11-16 GM Duramax 6.6L LML CP4 to CP3 Conversion Kit w/Pump (No Tuning Required)

The Industrial Injection CP4 to CP3 conversion kit is built around a robust Bosch CP3 injection pump, a well-known upgrade for Duramax 6.6L LML engines from 2011-2016. Many owners opt for this conversion because the factory CP4 pump can be prone to failure, especially when dealing with less-than-ideal fuel quality. By switching to the CP3, you're choosing a pump with a proven track record for durability and consistent fuel delivery, which can help prevent costly damage to your engine's fuel system.

This kit is designed to be a comprehensive solution, including the necessary components to swap the CP4 for the CP3. A key benefit is that it requires no additional tuning to function with your truck's factory computer. This means you can install the kit and get back on the road without needing to reprogram your engine's control module, simplifying the installation process significantly. The Bosch CP3 pump itself is a solid choice, known for its ability to handle a wide range of operating conditions and maintain precise fuel pressure, which is crucial for optimal engine performance and longevity.

When undertaking this conversion, ensure you have a clean workspace and follow the included instructions carefully. Replacing the injection pump is a critical job, and attention to detail will pay off in a reliable fuel system. This kit is a popular choice for owners looking to improve the reliability of their LML Duramax, offering peace of mind and a more dependable fuel supply for daily driving or heavy-duty use.
