Radium Fuel Cell Surge Tank (FCST), Walbro F90000267/274/285 E85, Pumps Not Included

The Fuel Cell Surge Tank is a drop-in fuel pump system for Radium Engineering's popular fuel cells or any cell that uses the industry standard 6x10 24-bolt fill plate bolt pattern. The FCST is designed to protect EFI vehicles that experience fuel starvation. It is NOT a glorified trap door box with baffles. It features a true dual-chamber fuel tank utilising a single lift pump and up to 3 surge tank pumps, all packaged inside the fuel cell. It provides all the benefits of a traditional external fuel surge tank without safety concerns and plumbing complexity.

8AN DSV (dynamic safety vent) valve
6x10 24-hole FKM gasket
