The DeatschWerks DW400 (9-403-1047) is a high-performance in-tank fuel pump designed to support high-horsepower applications while maintaining the integrity of your vehicle's factory fuel system. Delivering a massive 415LPH at 40 psi, this pump provides the necessary flow for forced induction and high-output naturally aspirated builds. It features a carbon commutator for E85 compatibility and an internal bypass valve to protect your engine's fuel system components.

This specific kit is engineered with a 1/8-inch venturi to ensure proper operation of the factory jet pump system, preventing fuel starvation during low-tank conditions or high-G cornering. The included 9-1047 installation kit provides the application-specific hardware needed to secure the pump within the OE fuel basket for a reliable, drop-in fitment.
