X2 Series Fuel Pump Module with Dual DW420 Pumps for 2008-21 WRX/STI, 2008-18 Forester, 2005-09 Legacy, 2008-14 Impreza

The DeatschWerks X2 Series Fuel Pump Module with Dual DW420 Pumps is engineered to provide high-flow fuel delivery for performance-focused Subaru applications. This complete module assembly uses two DW420 fuel pumps to support demanding engine builds while maintaining a practical in-tank installation. The integrated design helps simplify installation compared with assembling separate pump, hanger, and wiring components.

Part number DWK9-421-7050 is designed for select 2008–2021 Subaru WRX and STI models, 2008–2018 Forester models, 2005–2009 Legacy models, and 2008–2014 Impreza models. Fitment can vary by vehicle configuration, fuel system setup, and model-year application, so verify compatibility before installation. The module is intended for automotive use and is not CARB approved. Applicable emissions requirements and regional regulations should be confirmed before purchase or installation.

DeatschWerks builds this X2 module for reliable performance in high-demand fuel systems. Dual-pump operation provides substantial fuel-flow capacity for turbocharged and modified applications, while the purpose-built module supports a clean, organized installation inside the fuel tank. Professional installation is recommended, including inspection of the fuel system, electrical connections, fuel lines, and supporting components before operation.

What's Included: DeatschWerks X2 Series fuel pump module, two DW420 fuel pumps, and the integrated module assembly. Vehicle-specific installation hardware or additional fuel-system components may be required depending on the application.

Fitment: Select Subaru WRX, STI, Forester, Legacy, and Impreza applications. Confirm exact year, trim, engine, and fuel-system compatibility using the vehicle application information before ordering.
