DeatschWerks 01-05 Honda Civic/02-06 Acura RSX DW400 Pump Module & Return Kit w/CPE Fuel Lines

If you're working on a 2001-2005 Honda Civic Si or a 2002-2006 Acura RSX and need to upgrade your fuel system's capacity, this DeatschWerks DW400 pump module and return kit is a solid option. It's designed to replace your stock fuel pump assembly with a higher-flow unit, capable of supporting more demanding engine builds. This kit includes the DW400 pump module itself, along with a complete return-style plumbing kit featuring CPE fuel lines, giving you everything needed to get a more robust fuel delivery system installed.

DeatschWerks is known for making well-built fuel system components, and the DW400 pump is their answer for applications needing more fuel than stock. The kit comes with stainless steel CPE (Corrugated Stainless Steel) fuel lines, which are flexible and durable, making routing easier in tight engine bays. This setup is particularly useful if you're planning on adding more boost, upgrading injectors, or making other modifications that increase your engine's fuel requirements. The return-style setup allows for better fuel pressure control compared to a stock returnless system.

When installing this kit, remember that it's not CARB approved and cannot be shipped to California. It's a significant upgrade for performance-oriented builds, ensuring your engine receives the fuel it needs to perform reliably under increased load. Make sure to consult the manufacturer's installation instructions for specific details on fitting the module and routing the new fuel lines.
