Product Information

This DeatschWerks kit pairs the DW400 pump module for 1999-2004 Silverado and Sierra trucks with a complete return plumbing kit. The module is a plug-and-play replacement for the OE unit that more than doubles factory flow, retains the OE fuel level sender and uses a return-fed bucket for low-level pickup. The kit adds stainless braided CPE lines with an 8AN feed and 6AN return, a DWR1000 regulator, a fuel pressure gauge and a DW110 10-micron stainless filter. It supports 800+ hp on pump gas.
