Product Description

The DeatschWerks 9-101-1029 is a DW100 series 165lph in-tank electric fuel pump with install kit, engineered as a direct OE replacement for the 1990-1996 Chevrolet Corvette C4 equipped with the 5.7L L98 or LT1 V8. It drops directly into the factory fuel pump module without modification, making it a straightforward swap for a worn or failing stock pump. Note that this pump does not fit the ZR-1, which uses a different fuel delivery system built around the LT5 engine.

The DW100 uses a composite turbine impeller that is compatible with the pulse width modulated pump drivers found on C4 Corvette fuel systems, delivering quiet and reliable fuel flow at 165 lph. The computer-balanced armature minimizes NVH, and the encapsulated armature construction ensures compatibility with ethanol blends up to E25. For optimal pump performance, DeatschWerks recommends using 14-gauge wire to ensure maximum voltage delivery to the pump. The included 9-1029 application-specific install kit contains all hardware necessary to complete the installation.
