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.

DW300 series, 340lph in-tank fuel pump w/ install kit for 04-7 Cadillac CTS-V

Redesigned DeatschWerks DW300 in-tank electric fuel pumps flow 26 percent more at peak, and 20 percent greater on average than their predecessor, with no significant increase in current draw. The low amperage draw minimizes pump temperatures, maximizes pump life, and reduces stress on OE wiring.

In order to achieve a flatter flow curve, DeatschWerks uses a dual zone approach which increases flow where specifically engineered for high pressure, and limits flow at low pressure, thus achieving excellent performance and reliability.

The units are Ethanol compatible, have reliable and quiet turbine impellers, and work well with super or turbocharged applications. Get the flow to get up and go by installing DeatschWerks DW300 in-tank electric fuel pumps.
