DeatschWerks DW400 – DW’s Highest Flowing In-Tank Fuel Pump

Oklahoma City – October 17, 2017 – Over the past 7 years, DeatschWerks (DW) has grown their fuel pump line to include 12 unique models that provide a wide variety of flow and fitment options.  However, the ever-increasing power outputs of today’s aftermarket engines have created the need for a new in-tank pump with flow capabilities beyond anything currently available.  Today, DW is answering that call with the release of the DW400 in-tank pump.

The development of a 400+ LPH pump in a footprint small enough for in-tank use is a significant engineering feat.  To ensure success, DW turned to Bosch Automotive Aftermarket to find a solution.  DW and Bosch have a long-standing relationship which has resulted in several fuel injector products.  The DW400 represents the team’s first collaborative fuel pump product.  The pump is manufactured by Bosch in Germany.  Final QA, packaging, and sales are performed by DW in Oklahoma City, OK.

The DW400 surpasses the 400LPH benchmark by delivering an industry leading in-tank flow of 415LPH at 40psi.  Even more importantly, the DW400 delivers 31% more flow than its nearest competitor at pressures between 70 and 100 psi.  

The DW400 has a 46mm diameter and is compatible with pump gas, e85, and race fuels.  The pump is also compatible with pulse width modulated pump drivers.  The pump ships with a universal fitment kit which includes fuel hose, clamps, electrical harness, and filter.  As with all DW products, the pump is warrantied for 3-yrs to the original purchaser.
