DeatschWerks 415LPH DW400 In-Tank Fuel Pump w/ Universal Set Up Kit - 9-401-1001

DeatschWerks DW400 In-Tank Fuel Pump with Universal Install Kit (9-401-1001)

The highest-flowing in-tank pump on the market at 415 lph at 40 psi — but the flow number isn't the reason to pick it. DeatschWerks engineers the armature for torque bias, delays pressure relief activation, and maximizes impeller efficiency to produce an extremely flat flow curve. In practice that means it substantially outflows other 450-class pumps in the 70-100 psi range, which is exactly where a boosted EFI engine actually operates.

Single scroll composite turbine impeller with a computer-balanced armature for quiet operation and pulse width modulation compatibility. E85 compatibility is built in through carbon commutators and a fully encapsulated armature. Pump gas, E85, and race fuels are all in scope.

Rated to 120 psi maximum. Operating range 6 to 18 volts. Current draw is 16.5 amps at 40 psi and 13.5V. Outlet is a 3/8" hose clamp fitting. 46mm diameter body.

Plan for the current draw. 16.5 amps is not a stock fuel pump circuit. This needs a relay and heavier gauge wire, or you'll lose fuel pressure at high duty and chase a lean condition that isn't the pump's fault.

Check your hanger before ordering. This is a 46mm pump, not the 39/50mm footprint most aftermarket hangers are cut for. Confirm your hanger accepts a 46mm body or has the correct bracket available.

Includes the pump and a universal fitment kit with fuel hose, clamps, electrical pigtail connector, and pump inlet filter. 3-year warranty.
