Product Details

If you're looking to significantly upgrade the fuel system on your 8th generation 2006-2011 Honda Civic Si, this DeatschWerks DW400 Pump Module and Return Kit is a solid choice. This kit bundles the high-flow DW400 fuel pump module with a complete return line setup, specifically designed for the K20 engine found in the Si models. It's built to handle the demands of a performance-oriented fuel system, ensuring your engine gets the fuel it needs when you push it hard.

What you get in this package is the DW400 fuel pump module itself, which is known for its high flow rate, along with all the necessary components for a return-style fuel system. This includes CPE (Coated Stainless Steel Braided) fuel lines, which offer excellent resistance to fuel and heat, along with the fittings and adapters needed to plumb it into your Civic Si. This setup is a step up from stock, designed to support more aggressive engine modifications and ensure consistent fuel pressure under demanding conditions. The module is designed as a direct fit for the factory fuel tank, simplifying the installation process compared to universal pump setups.

This kit is a comprehensive solution for anyone serious about their Civic Si's fuel delivery. It's important to note that this kit is not CARB approved and cannot be shipped to California. Make sure to consult the manufacturer's installation instructions for specific details regarding the setup and any additional components that might be recommended for your particular build.
