2018-2023 FORD MUSTANG DW400 FUEL PUMP REPLACEMENT KIT

The DW400 Fuel Pump Replacement Kit is Whipple's in-tank replacement fuel pump solution for 2018-2023 Ford Mustang applications. In-tank pump placement offers major advantages for high-performance fuel systems, including improved reliability, reduced complexity, quieter operation, and better overall cost efficiency compared to external pump arrangements.

Rated at 415 liters per hour, the DW400 is a high-flow in-tank fuel pump designed to support demanding performance combinations. In the proper application, it can support up to 1000 horsepower on gasoline and up to 750 horsepower on E85, making it a strong replacement option for Mustang owners needing additional fuel system capacity.

As a direct replacement for the OE pump, this kit allows the user to retain key factory fuel system benefits, including excellent low-fuel pickup, pump programmability through the OE fuel pump controller, and retention of the factory fuel lines. This makes it an effective solution for customers looking to replace or upgrade the in-tank pump while maintaining OE-style system integration.

Each kit includes the DW400 fuel pump plus the application-specific components needed for installation, including hose, clamps, electrical harness, filter, and any required specialty parts. Modification to the pump assembly is required during installation.
