DW400 Universal In-Tank Fuel
Pump by DeatschWerks
Over
the past 7 years, we have grown our 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, we are 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, 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
High Flow at High Pressure
The
DW400 is the highest flowing brushed in-tank pump on the market. But the
flowrate of 500LPH at 0psi and 415LPH at 40psi only tells part of the
story. Much more important than high-flow at low pressure is a pump’s
ability to hold on to that flow under high loads of fuel pressure and boost
pressure. The pressure range of 70-100 psi is where modern boosted EFI
engines make their peak power and thus need their pumps to perform at their
best. Since the DW400 was engineered with this in mind, it was no surprise
that it significantly outperformed the benchmarked Walbro 450 “e85”.
During side-by-side comparisons, the DW400 did flow 5% more at 40 psi, but more
meaningfully, flowed an average of 31% more in the 70-100 psi range
