The DeatschWerks DW400 Performance Module (Part # 9‑437‑7220) is a high performance drop‑in replacement fuel pump module for the 2003‑2009 Nissan 350Z and 2003‑2008 Infiniti G35 with the 3.5L V6 (VQ35DE / VQ35HR) engines. It is engineered to replace the factory low‑pressure module, delivering approximately 195% more fuel flow (≈ 300 L/h) while maintaining OEM functionality including level sensor, harness connector, fuel basket, and mounting points. This makes it ideal for built or heavily modified VQ engines requiring more fuel delivery for higher horsepower, ethanol blends (E85), or forced induction support.

Installation is straightforward as it is a direct replacement module; however, to ensure the pump receives full voltage under load, upgrading the power feed wiring (using 12‑gauge hardwire) is strongly recommended. It is not CARB‑legal, so vehicles in California or states with equivalent emissions laws cannot use this part. Fitment is confirmed through models up to 2009 for 350Z and 2008 for G35.
