Product Description

The Radium Engineering 20-1991-00 FCST-X Fuel Cell Surge Tank is designed for high-performance fuel systems where every drop and delivery counts. With support for up to three surge pumps and one lift pump (installation applicable), this kit gives the serious builder a robust foundation for big-power or race-specific builds. By combining advanced one-way fill valves, a merged high-flow outlet and service-friendly access, it tackles the common problem of fuel starvation under high-G cornering, hard launches or sustained boost runs.

Installation is flexible: the unit is compatible with competition-grade fuel cells (6"x10" flange), can be paired with Bosch BR540/DW400 series pumps or similar, and supports ethanol-capable plumbing. If you're constructing a drag car, road-race machine or high-boost track platform, this surge tank offers the scalability, performance and reliability to match your ambitions.
