Description

DeatschWerks DW420 in-tank electric fuel pumps are a popular choice for ethanol applications or wherever the highest flowing standard fitment in-tank pump is needed. Quiet operation and pulse width modulation compatibility are delivered via the turbine impeller and computer-balanced armature. Ethanol compatibility is built-in via the carbon commutators and a fully encapsulated armature.

DeatschWerks has engineered their fuel pumps to maximize flow at higher pressures. By designing the armature for torque bias, delaying pressure relief activation, and maximizing impeller efficiency, DW has created a line of pumps with an extremely flat flow curve. Higher flow at higher pressure delivers the fuel your engine demands.

All DW pump designs go through 1,000 hours of endurance bench testing in a number of fuels to find and eliminate common modes of failures. Upon success, the pump design is in-car tested for several months in real-world conditions before production is approved. Each fuel pump is flow tested at pressure to make doubly sure that it meets DW's high standards of performance before it is labeled and packaged.

Product details:

* Application specific fitment—per vehicle year, make, and model
* Composite impeller—made of a lightweight composite that is both efficient and impervious to the corrosive nature of ethanol
* Encapsulated armature—DW pump motor armatures are fully encapsulated to protect the copper windings from ethanol deterioration
* Carbon commutators and brushes resists aggressive fuels, reduces electric draw, and leads to a much longer life especially in high-heat and high-pressure conditions
