DW400 Fuel Pump Module

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.
