Product Description

The DeatschWerks 9-402-1048 is a high-performance DW400 series in-tank electric fuel pump engineered to support increased fuel demands over stock units. With a flow rate of approximately 415 liters per hour (110 gallons per hour), this pump provides enhanced fuel delivery for performance-oriented engines, particularly in sports cars like the Chevrolet Corvette C5 and C6 (2001-2013). Designed for use with compatible fuel modules, the DW400 combines quiet operation with robust performance across a wide voltage range.

This fuel pump is compatible with gasoline, ethanol (E85), and many race fuel blends, making it suitable for both street and high-output applications. Its compact design fits within tight OEM tank housings where larger pumps struggle. The turbine impeller and balanced armature ensure stable delivery and efficient operation, while its high pressure rating supports demanding fuel system requirements. For optimal performance, verify that your vehicle's fuel tank and electrical system are compatible with the DW400 specifications before installation.
