DW400 In-Tank Fuel Pump w/ 9-1044 Install Kit

The DeatschWerks DW400 In-Tank Fuel Pump with 9-1044 Install Kit is a 415 liters-per-hour electric fuel delivery system engineered for small-block Ford performance applications, particularly 1985–1997 Ford Mustangs equipped with Cobra drivetrains. This complete kit combines a proven high-flow pump with a purpose-matched fuel line and component assembly, eliminating guesswork during installation and ensuring compatible fuel pressure delivery across the ignition range.

The 415 lph flow rate addresses the fuel demands of modified and stock small-block engines running improved carburetor tuning, nitrous oxide systems, or forced-induction setups without requiring external pump mounting or complex plumbing modifications. In-tank installation keeps the pump submerged in fuel for consistent cooling and noise isolation, a standard approach in fuel system design that prevents vapor lock and extends pump longevity. Compatibility with both gasoline and ethanol blends provides flexibility for fuel choice without requiring component swaps. The included 9-1044 install kit contains all OEM-equivalent fittings, hoses, and electrical connectors specific to the Mustang platform, reducing installation time and compatibility risk.

This kit is the choice for Mustang enthusiasts upgrading fuel system capacity for reliable cold-start performance, sustained high-rpm running, and forced-air applications where stock fuel delivery cannot sustain demand. Restorers and performance builders working on 1985–1997 small-block Cobra conversions benefit from the kit's application-specific design, which eliminates cross-platform adapter hunting and reduces fitment errors common with generic aftermarket pumps.

DeatschWerks is recognized in the fuel system category for OEM-level precision and flow-rate accuracy, making this DW400 fuel pump system a trusted upgrade for builders who prioritize reliability alongside performance gains in street and strip Mustang applications.
