Deatschwerks DW300 High Flow In-Tank Fuel Pump + Install Kit Infiniti G35 2003-2008 / Nissan 350Z 2003-2009 | 9-301s-1005

The DeatschWerks DW300 fuel pump is a high-performance in-tank solution designed to deliver increased fuel flow without compromising reliability. With a redesigned internal architecture, the DW300 provides significantly more flow while maintaining low current draw—making it ideal for turbocharged and supercharged applications.

Performance Overview

The DW300 is engineered with a dual-zone flow strategy, increasing fuel delivery where high-performance engines need it most—under boost and elevated fuel pressures. At the same time, flow is controlled at lower pressures to reduce heat buildup, improving long-term reliability.
