Description

DeatschWerks, LLC provides high-performance fuel system solutions for the automotive aftermarket. Located in Oklahoma City, OK, DW houses all of the company?s functions including design, end-manufacturing, quality assurance, sales, marketing, and administration in its 36,000sf facility. DeatschWerks? roots were established in 2004 by offering high flow drop-in fitment fuel injectors. In 2009 DW expanded into fuel pumps with the DW300, the highest flowing in-tank fuel pump of its time. Since then, DW has developed a wide range of innovative fuel system components which include in-tank and in-line pumps, surge tanks, fuel rails, fuel filters, pressure regulators, and fuel-specific lines, fittings, and adaptors. Today, the DeatschWerks line-up of fuel system components includes over 800 SKU?s covering Sport Compact, Modern Muscle, Euro, and Powersport applications.

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.
