DeatschWerks DW440 brushless in-tank electric fuel pumps have a total height of only 4 in., making them easy to retrofit into any OE pump module. Brushless technology reduces friction and heat, increases efficiency, vastly improves pump lifespan in ethanol and methanol fuels—and allows higher voltage inputs for increased flow! These pumps move 440 lph of fuel at 40 psi. Each fuel pump includes a controller, which accepts an 8-22 V DC input and creates a digital signal to allow precise speed and torque control. The controllers are available in three configurations: single speed, dual speed, and PWM-controlled. Controller are designed to be used with voltage boosters, and the pump kits also include bulkhead wiring. Features Capable of flowing 440 LPH at 40 psi Capable of supporting 1000HP on gasoline and 750 HP on E85 Brushless design Dual-speed controller allows you to operate at a low duty cycle during normal driving conditions and full-cycle under heavy loads
