The DeatschWerks DW400 Fuel Pump Module and Return Kit is a comprehensive fueling solution designed for high-horsepower K-series builds. This system replaces the restrictive factory fuel setup with a high-flow DW400 in-tank pump and a complete return-style conversion, providing the necessary flow and pressure stability for forced induction or ethanol-based applications.

This kit features PTFE-lined fuel lines, which offer superior chemical resistance and zero vapor permeation compared to traditional rubber lines, making them fully compatible with E85. By converting to a return system, tuners gain precise control over fuel pressure through an external regulator, overcoming the limitations of the OE returnless design. The DW400 pump stands as DeatschWerks' highest-flowing in-tank unit, engineered to maintain consistent volume under high-load conditions.

  • DW400 high-flow in-tank fuel pump
  • PTFE fuel lines for maximum durability and fuel compatibility
  • Complete return-style conversion hardware
  • Designed specifically for the 8th Gen Civic Si chassis
  • Manufacturer Part Number: 9-401-608-7041
