Product Description

The DeatschWerks 6-251-25ST is a 2.5-liter modular surge tank built for racing and high-horsepower EFI applications where standard in-tank pumps fall short. By maintaining a dedicated fuel reserve, it eliminates fuel starvation under hard cornering, aggressive launches, and low tank levels - a common failure point in performance builds. The included DW250iL in-line pump is capable of supporting approximately 550HP on its own, with the tank configurable for a second pump if your power goals demand more.

The submerged pump design keeps the pump cooled and quieter than external alternatives, while the anodized aluminum body ensures long-term compatibility with E85 and gasoline. Both vertical and horizontal mounting are supported, giving builders flexibility in tight engine bay or chassis mounting locations.
