DeatschWerks DW400 In-Tank Fuel Pump w/ Set Up Kit

Part #: 9-401-1001

The development of a 400+ LPH pump in a footprint small enough for in-tank use is a significant engineering feat. To ensure success, we 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, the Walbro 450 "e85", 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.

All this performance is packaged into a 46mm body which will fit into many OE aftermarket pump modules. The 46mm body is a 16% smaller footprint than the Walbro 450 “e85” 55mm bell bottom. However, it is also a 7mm diameter increase from a standard 39mm pump. Therefore, modifications may be needed to fit the pump into OE modules. The DW400 includes a universal install kit containing a filter, electrical harness, hose, and clamps.
