The DeatschWerks DW400 pump module and return-line kit upgrades the in-tank fueling on the 2006-2011 Honda Civic Si (K20). It pairs the 415 LPH DW400 in-tank pump with a complete PTFE fuel line return system for high-horsepower and E85 builds. This is a direct-fit module assembly built for the K20 chassis. PTFE lines resist permeation and handle ethanol-blended fuels.
