Product Details

If you're looking to upgrade the fuel system on your 1999-2004 GM truck, this DeatschWerks DW400 pump module is a solid choice. It's designed to handle increased fuel demands, making it a popular option for modified V8 engines like the 4.8L, 5.3L, and 6.0L found in models like the Silverado 1500 and Sierra 2500. This module replaces your stock fuel pump assembly and includes everything needed to get more fuel flowing to your engine.

The DW400 pump itself is known for its high flow rate, capable of supporting significant horsepower increases. DeatschWerks builds these modules with their CPE (Corrugated Polymer E-braid) fuel lines, which are fuel-resistant and designed for durability. This kit is a complete package, aiming to simplify the installation process for a more robust fuel delivery system. It’s a well-built unit that addresses the needs of trucks that are pushing beyond their original fuel system's capabilities.

This module is a direct fit for a range of GM trucks from 1999 to 2004, including popular models like the Chevrolet Silverado 1500 and GMC Sierra 1500. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure your vehicle is not a flex-fuel model, as this pump module is not compatible with those applications.
