Product Description

The DeatschWerks 9-401-7010 is a DW400 series high-performance fuel pump module assembly for 1999-2004 Chevrolet Silverado and GMC Sierra 1500/2500/3500 trucks equipped with V8 gasoline engines (4.8L, 5.3L, 6.0L), excluding Flex Fuel models. The complete module assembly drops directly into the factory fuel tank as a full replacement for the OE unit, delivering 415 LPH of fuel flow -- enough to support up to 750 horsepower in naturally aspirated gasoline applications at 13.5 volts.

Designed for trucks running performance modifications such as cam swaps, forced induction, or nitrous that demand more fuel than the factory pump can deliver, the DW400 module provides the volume and pressure headroom needed to keep the engine safely fueled under full load. Compatible with both gasoline and E85 ethanol blends. The OEM-style electrical connector provides plug-and-play wiring integration with no splicing or adapter harnesses. For applications requiring a dedicated return fuel line, the CPE fuel line version (9-401-603-7010) is available. Designed, manufactured, and quality tested at DeatschWerks' facility in Oklahoma City, Oklahoma.
