DeatschWerks 06-11 Honda Civic Si K20 DW400 Pump Module

Power Shortage? Meet the High-Performance Solution

If you’ve pushed the stock fuel pump on your 2006-2011 Honda Civic Si to its limits, chances are you’re experiencing fuel delivery issues—especially as you aim to crank up horsepower. Factory fuel pumps simply aren’t designed to handle the demands of high-horsepower applications, particularly if you’re running a turbo setup or other heavy modifications. The limitations of the stock fuel pump can hold your performance back, preventing your engine from reaching its true potential. Here’s where the DeatschWerks DW400 Pump Module steps in, purpose-built to support your high-power goals with a flow rate that leaves the factory pump in the dust.

The DW400 Pump Module: Built to Perform Under Pressure

DeatschWerks developed the DW400 Fuel Pump Module with high-performance builds in mind, delivering a substantial 415 liters per hour (lph) flow rate. That’s ample power to feed modified engines craving more fuel to keep the torque rolling. This pump module not only enhances fuel delivery but is also compatible with a wide range of fuel types—be it standard pump gas, race fuel, or e85. Engineered to retain all original module functionality, the DW400 integrates seamlessly into your 8th-generation Civic Si’s existing setup. It retains the OEM plug-and-play harness connector, fuel level sender, and fuel surge bucket, making it straightforward to install while preserving all OEM features.

Seamless Installation and Versatile Fuel Compatibility

Installation of the DW400 Pump Module is straightforward and requires no extensive modifications. The package includes a comprehensive fitment kit with all the hoses, clamps, filters, and connectors needed for a smooth installation, saving you the hassle of hunting down individual components. This module is designed to work with a -6AN feed line, and it cleverly utilizes the original feed line as a return, allowing for flexibility in plumbing configurations. Optional plumbing kits with regulators and filtration are also available to tailor the setup to your exact needs. DeatschWerks’ attention to detail ensures that once installed, your Civic is ready to unleash power reliably and consistently, whether on the street or the track.
