DeatschWerks Fuel Pump Module With Dual DW400 Pumps 800LPH+ Return Style
Part Number: 9-401-7003
If you're looking for a drop in solution to supply enough fuel for over 1000whp this is the system for you. The pair of these pumps supply over 800 liters per hour of fuel flow and do so without the typical fuel sloshing issues of other systems thanks to the reuse of the OEM fuel bucket. This kit requires the use of a fuel pressure regulator and return fuel line, sold separately.
About the DW400 pumps,
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.
Bosch Quality
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 our friends at Bosch Automotive Aftermarket to collaborate on a solution. Our target was simple yet challenging…
Outflow all other in-tank brushed pumps on the market
Maintain flow under high loads of fuel pressure and boost pressure
Withstand fuels of all types including ethanol and race gas
The resulting pump exceeded our high expectations not only for performance, but also for quality. The DW400 exemplifies the high engineering and manufacturing standards of Bosch, GMBH. Features include: carbon commutators and brushes, fully encapsulated and machine balanced armature, PWM compatible composite turbine impeller, and die cast metal inlet endcap. The DW400 is manufactured in Germany and then delivered to Oklahoma City, OK where DW performs final QA testing, packaging, and distribution.
