Product Details

If you're looking to upgrade the fuel system on your 2005-2013 Chevrolet Silverado 1500 or GMC Sierra, this DeatschWerks DW400 Pump Module with CPE fuel lines is a solid option. This module is designed to handle increased fuel demands, making it a great choice for modified trucks or those pushing their engines harder. It replaces your stock fuel pump assembly with a higher-flow unit and includes specialized fuel lines to ensure proper connection and performance.

The DW400 pump itself is known for its impressive flow rate, capable of supporting significant horsepower increases. DeatschWerks builds these modules with their own high-performance pumps and includes a return-style kit with CPE (Chlorinated Polyethylene) fuel lines. CPE lines are chosen for their resistance to modern fuel blends and their durability under pressure. This setup ensures that your fuel system can keep up with your engine's needs, providing consistent fuel pressure and volume even under demanding conditions. The module is designed as a direct replacement for the factory unit, simplifying the installation process.

This kit is specifically designed for V8 engines in the 4.8L, 5.3L, and 6.0L range, excluding flex-fuel models. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you check your vehicle's specific configuration before ordering.
