Product Description

The DeatschWerks 9-401-604-7016 is an advanced fuel delivery upgrade built for the 2005-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 with 4.8L, 5.3L, or 6.0L V8 gasoline engines. Combining an X3 triple-pump module with three DW400 pumps and PTFE 8AN plumbing, this kit delivers massively increased fuel flow to support high horsepower, forced induction, or high ethanol blend setups. It retains all the OEM features such as the fuel level sensor and tank surge capacity, making it a potent yet comprehensive upgrade over the stock fuel module.

Ideal for performance builds where the factory fuel system becomes a bottleneck, this kit ensures that under load the fuel supply remains stable. Installation requires removing the existing fuel module from the tank, fitting the new bucket with the X3 module, connecting the included plumbing, and upgrading the wiring (10-gauge hardwire recommended) for full performance. Proper fuel filtration downstream is essential, as is verifying compatibility on Flex Fuel or modified tanks.
