DeatschWerks, LLC provides high-performance fuel system solutions for the automotive aftermarket. Located in Oklahoma City, OK, DW houses all of the company?s functions including design, end-manufacturing, quality assurance, sales, marketing, and administration in its 36,000sf facility. DeatschWerks? roots were established in 2004 by offering high flow drop-in fitment fuel injectors. In 2009 DW expanded into fuel pumps with the DW300, the highest flowing in-tank fuel pump of its time. Since then, DW has developed a wide range of innovative fuel system components which include in-tank and in-line pumps, surge tanks, fuel rails, fuel filters, pressure regulators, and fuel-specific lines, fittings, and adaptors. Today, the DeatschWerks line-up of fuel system components includes over 800 SKU?s covering Sport Compact, Modern Muscle, Euro, and Powersport applications.

The DeatschWerks DWK9-401-607-7041 DW400 Pump Module and Return Kit is designed for 2006-2011 Honda Civic Si models equipped with the K20 engine. This complete fuel system upgrade combines a high-flow DW400 in-tank fuel pump module with a return-style fuel system and CPE fuel lines, providing the flow capacity and component compatibility needed for demanding street, track, and performance applications.

DeatschWerks developed this kit to simplify installation while supporting upgraded fuel system requirements. The integrated pump module is engineered for reliable in-tank operation, while the included return components and fuel-specific CPE lines help provide a durable path for fuel delivery. This design is well suited for applications requiring improved fuel volume and more consistent fuel pressure than the original equipment system can provide.

The DWK9-401-607-7041 kit is intended for automotive use and fits 2006, 2007, 2008, 2009, 2010, and 2011 Honda Civic Si K20 applications. It is not CARB approved, and California emissions compliance should be verified before installation. Professional installation and appropriate fuel system calibration are recommended to ensure proper operation with the vehicle’s engine management system and supporting performance modifications.
