Product Overview

DeatschWerks in-tank fuel pumps are manufactured with a quiet and reliable turbine impeller which is compatible with pulse width modulated pump drivers. These pumps are also built with carbon commutators and fully encapsulated armatures for ethanol compatibility. DW's high-torque motors maintain flow at higher pressure better than competitors' pumps. Low amperage draw minimizes pump temperatures, maximizes pump life and reduces stress on OE wiring. Vehicle-specific pumps include a fitment kit assembled with everything you need for your application. Vehicle specific install instructions are also available on our website to walk you step-by-step through the installation process.

Fuel Pump TECH SHEETS and INSTALLATION GUIDES can be found at "deatschwerks.com":http://www.deatschwerks.com under the Support tab.

All DW fuel pumps are backed by a 3-year no fault warranty.
