Overview

The DeatschWerks DW400 Fuel Pump Module Assembly is a high-performance upgrade designed for 1999-2003 Chevrolet Silverado and GMC Sierra trucks. It offers enhanced fuel flow to support modified engines and provides OEM-quality fitment.

This fuel pump module is capable of supporting up to 750 horsepower in naturally aspirated gasoline applications. It delivers 415 LPH of fuel flow at 40 psi and is compatible with E85 fuel. The assembly retains the OE-compatible fuel level sender, uses a venturi bucket for low-level fuel pickup, and retains factory fuel line and vent connections.
Show original supplier description
The DeatschWerks DW400 Fuel Pump Module is engineered to provide enhanced fuel delivery for 1999-2004 Chevrolet Silverado and GMC Sierra 1500, 2500, and 3500 models equipped with V8 engines (4.8L, 5.3L, 6.0L). This high-performance unit is ethanol compatible, allowing for the use of various fuel blends. Constructed with a single scroll composite turbine, the DW400 is designed for quiet and reliable operation. Its robust design aims to improve the overall performance of your vehicle's fuel delivery system. This specific module is explicitly stated to exclude Flex Fuel models, ensuring proper fitment and function. When installing this fuel pump module, it is important to verify fitment with your specific vehicle configuration. While the product page highlights compatibility for the specified truck models and engine sizes, always confirm that your vehicle meets the application requirements before purchase. For optimal performance, a 10-gauge hardwire kit is strongly recommended to ensure maximum voltage reaches the pump.
