DeatschWerks 6-551-30ST 3.0L Staged Surge Tank with Dual DW550 In-Line Fuel Pumps

The DeatschWerks 6-551-30ST is a 3.0-liter staged surge tank pre-configured with dual DW550 in-line fuel pumps, engineered to deliver massive, stable fuel flow under high-G racing conditions and extreme off-road angles to eliminate fuel starvation. This universal system is purpose-built for high-horsepower builds where traditional in-tank pump setups fall short.

Unlike conventional surge tank designs, the DW 3.0L Staged Surge Tank offers unmatched installation flexibility with multiple mounting configurations and a pass-through plumbing layout, making integration straightforward in both custom and production-based fuel systems. Moving both the pump and filtration functions inside the surge tank results in a compact footprint, reduced pump noise, and a cleaner engine bay installation.
