DeatschWerks DW400 Fuel Pump Module and Return Kit with CPE Fuel Lines for 2006-2011 Honda Civic Si (K20)
$1,049.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2006-2011 Honda Civic Si models equipped with the K20 engine.
The DeatschWerks DW400 Fuel Pump Module and Return Kit is a comprehensive fueling solution designed for high-output 8th Generation Civic Si builds. This kit facilitates the transition from a restrictive factory returnless system to a high-flow return-style setup, providing the volume and pressure stability required for forced induction or ethanol-tuned applications.
At the heart of the system is the DW400 in-tank pump, known for delivering industry-leading flow rates within a modular drop-in design. The kit is supplied with durable, chemical-resistant CPE fuel lines and precision-engineered fittings to ensure a secure, leak-free installation. By replacing the OE pump assembly with this purpose-built module, you eliminate fueling bottlenecks and provide your K-Series engine with the overhead needed for serious performance gains.
- Manufacturer Part Number: 9-401-607-7041
- Includes DW400 series high-flow in-tank fuel pump
- Complete return-style conversion plumbing and hardware
- High-quality CPE fuel lines for chemical and heat resistance
