Product Description

The Radium Engineering 20-1992-00 FCST-X Fuel Cell Surge Tank is a high-performance solution for competition-grade fuel systems, built around the needs of high-flow, high-G, or sustained-boost applications. With a dedicated surge tank chamber integrated into the fuel cell module, this unit ensures that the surge pump(s) remain fed even during extreme cornering, launches or elevation changes - reducing the risk of fuel starvation and maintaining steady rail pressure in tuned or racing engines. :contentReference[oaicite:14]{index=14}

This version is supplied without internal pumps, giving you the flexibility to choose your own lift and surge pumps based on your engine's fuel demand. It uses a single high-flow 10AN outlet for simplified plumbing, adheres to motorsport standard drop-in tank protocols (6"x10", 24-bolt flange) and offers adaptability for alternative fuels like E85 or methanol with proper system configuration. Whether building a purpose-built racecar, high-power street machine or endurance rig, the 20-1992-00 FCST-X provides a scalable foundation for reliable fuel delivery under serious performance conditions.
