Show original supplier description
The DeatschWerks DW400 is an in-tank electric fuel pump engineered to meet the demands of modern high-performance engines. This pump provides an industry-leading flow rate of 415 liters per hour at 40 psi, significantly outperforming other pumps in the critical 70-100 psi range used by many boosted EFI applications. Designed for versatility and reliability, the DW400 pump is compatible with a wide range of fuels, including gasoline, E85, and various race fuels. It also supports pulse width modulated (PWM) pump drivers, offering advanced control capabilities. Its compact 46mm diameter allows for fitment into diverse fuel tanks with minimal modification. This model includes a comprehensive universal installation kit. The kit contains all necessary components for a straightforward setup, such as fuel hose, clamps, an electrical pigtail connector, and a pump inlet filter. The universal nature of the kit means that while it provides the core components, some custom mounting solutions and integration into your existing fuel system may be required by the end user. The DW400 is presented as a solution for high-performance vehicles, from daily drivers to track cars, that require substantially more fuel delivery than stock. Its robust construction is tested for exceptional reliability and consistent performance under demanding conditions, reducing the risk of fuel starvation during high-load operations.
