Description
Engineered for High-Horsepower Demands. At the core of the DeatschWerks X3 Series Fuel Pump Module is a trio of DW400 electric fuel pumps, delivering a combined flow of 1,245 liters per hour, capable of supporting engines producing over 1,700 horsepower on pump gas. This immense capacity makes it a must-have for forced induction configurations—turbocharged, supercharged, or nitrous-fed builds that require relentless fuel flow under sustained wide-open throttle.
Built to Last. Precision-machined from aircraft-grade billet aluminum, the X3 fuel module offers incredible rigidity and thermal stability. This construction ensures exceptional resistance to vibration, pressure fluctuation, and fuel system corrosion. Whether you're pushing limits at the drag strip or logging hard miles on the street, this DeatschWerks X3 Series Fuel Pump Module is built to maintain performance where lesser components fall short.
Consistent Fuel Pressure. To prevent the dreaded fuel starvation that can occur during aggressive cornering, braking, or acceleration, the DeatschWerks X3 Series Fuel Pump Module incorporates an OEM-style surge bucket. This integrated feature helps to isolate and retain fuel around the pump inlets, preventing aeration and ensuring uninterrupted delivery of fuel to the engine.
Track-Ready Flow with Street-Level Refinement. Designed for plug-and-play functionality with select OE applications and aftermarket performance systems, the DeatschWerks X3 Series Fuel Pump Module integrates seamlessly into your existing fuel system architecture. Optional PWM compatibility and wiring solutions provide installation flexibility for both street-driven and motorsport builds.
Installation. Putting this DeatschWerks X3 Series Fuel Pump Module with Triple DW400s Pump on your Mustang GT takes 3 hours to install.
Warranty. There is a 3-year limited warranty on this product.
Application. The DeatschWerks X3 Series Fuel Pump Module with Triple DW400s Pump fits 1998-2004 Mustang GT models.
