Merged single 10AN ORB female threaded outlet.Over the years, Radium Engineering has continued to refine the FCST into a robust and highly functional piece of hardware. This dynamic sequence is all done inside the safety of a fuel cell. If this happens, each fill valve opens and sends 355LPH of fuel (1065LPH total) into the surge tank until fuel level reaches an equilibrium.Įxcess fuel in the surge tank simply overflows back into the fuel cell. These 1-way FKM fill valves are sealed shut unless the fuel level in the cell rises above the fuel level in the surge tank. The return from the pressure regulator is also routed to the surge tank canister to help keep it full.Īs shown on picture, there are 3 fill valves integrated to the bottom of the surge tank. If the lift pump starves, the volume inside the surge tank canister will keep the surge tank pumps fed and the engine supplied with fuel. Inside the surge tank canister, up to 3 EFI fuel pumps can be used to feed high pressure fuel to the engine. The cell depth must be at least 7.7" (196mm) measured from the outer top face to the internal bottom face.Ī lift pump scavenges fuel from the bottom of the fuel cell and pumps it into the 2L surge tank.The opening must be on the top face of the fuel cell (i.e.The cell must have the industry standard 6"x10" 24-bolt flange opening.
#RADIUM AUTO FUEL CELL INSTALL#
To install a Radium Engineering FCST into a fuel cell, the following criteria must be met: It provides all the benefits of a traditional external fuel surge tank without safety concerns and plumbing complexity. It features a true dual-chamber fuel tank utilizing a single lift pump and up to 3 surge tank pumps all packaged inside the fuel cell. It is NOT a glorified trap door box with baffles. The FCST is designed to protect EFI vehicles that experience fuel starvation. 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.
