Product Description

The DeatschWerks 9-305-1035 DW300M 340 LPH Dual Fuel Pump Kit is engineered as a high-flow performance upgrade for the Ford Mustang Shelby GT500 and GT500KR models from 2007 through 2012. This dual pump kit delivers approximately 340 liters per hour per pump, offering enhanced fuel delivery capacity for high-power naturally aspirated and forced induction builds. The DW300M pumps feature quiet turbine impellers and robust motor designs that maintain consistent flow across a range of pressures, supporting improved fueling for increased horsepower applications while retaining smooth street performance.

Each pump drops directly into the OEM in-tank fuel module using the included vehicle-specific install kits, providing a near-plug-and-play solution that does not require extensive modification. Designed for use with gasoline and ethanol blends including E85, this dual pump setup supports the higher fuel demands of modified GT500 engines while maintaining reliability and stable pressure under load. Always verify compatibility with your fuel module and electrical system before installation to ensure correct fitment and performance.
