DeatschWerks E85 DW400 415lph in-tank fuel pump Universal 9-401-1001
April 30, 2021 - deatschwerks
DW400 series, 415lph in-tank fuel pump w /Universal Install Kit. 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. 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. 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 2. Maintain flow under high loads of fuel pressure and boost pressure 3. Withstand fuels of all types including ethanol and race gas. 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. Wiring – A 400+ LPH pump draws substantial current (16-20 amps at typical operating pressures). Make sure your chassis wiring is up to the task of delivering this much current. Size – The DW400 is a 46mm diameter pump. Standard in-tank pumps are 39mm diameter. Modifications to the fuel pump module will be necessary on some applications. Universal Fitment – Unlike other DW in-tank pumps, The DW400 is not an application-specific fitment pump. Check-valve – the DW400 does not have in internal check valve. An in-line check valve may be necessary for easy engine starts in some applications.
