DeatschWerks DW400 Fuel Pump Module for 2005-2009 Chevrolet Silverado & GMC Sierra 1500/2500 HD/3500 (9-401-7012)

Fits 2005-2009 Chevrolet Silverado and GMC Sierra 1500, 2500 HD, and 3500 models.

The DeatschWerks DW400 fuel pump module is a high-performance, drop-in solution designed to meet the increased fuel demands of forced induction and high-horsepower GM truck builds. By integrating the DW400 series pump—the highest-flowing brush-style in-tank pump available—into a vehicle-specific hanger assembly, DeatschWerks provides a reliable fueling path that maintains factory-level fitment and tank integration.

This module replaces the restrictive OE unit, allowing for significantly higher flow rates without the need for extensive fuel system plumbing modifications. It is engineered to provide consistent fuel delivery for LS-based engines under high load, ensuring your fuel system can keep up with performance tuning and hardware upgrades.
