Product Description

The Radium Engineering 20-1990-03 FCST-X Surge Tank is a professional-grade solution for performance builds and motorsport applications where fuel delivery cannot be compromised. With three high-flow surge pumps and a dedicated lift pump pre-installed, this kit addresses the challenges of fuel starvation during high-G maneuvering, long runs or forced-induction setups. Its single 10 AN outlet simplifies plumbing while its one-way fill valves maintain surge tank volume under dynamic conditions.

Installation is universal: the unit is designed for fuel cells with the top-mounted 6"x10" flange and 24-bolt pattern, requiring no major tank modification. Paired with appropriate pumps, hoses and return plumbing, the 20-1990-03 offers tuners, fabricators and racing teams a turnkey high-flow fuel system component ready for demanding use. Whether for drag, road-race or endurance applications, this surge tank system helps ensure consistent fuel pressure, cleaner plumbing and high reliability.
