Links for compatible fillers (not included), Direct Mount or Remote Mount 8AN male pump out fitting (other sizes can be utilized) 6AN male return fitting (other sizes can be utilized) The following comes standard with every FCST variation configured per part number Optional fuel surge tank level switch and diagnostic LED failsafe port (shown below). Dynamic safety vent valve with rollover protection and fuel fill shut-off. Fuel compatibility: leaded and unleaded gasoline, methanol, ethanol, E85, etc. Full CNC aluminum construction with anodized surfacing for superior corrosion resistance. Simplified servicing features eliminating nylon sealing washers and fuel cell retaining brackets. Hermetically sealed high-current stainless steel electrical studs capable of handling all pumps.
Multiple fuel pump options including gerotor, turbine, and brushless DC motor pumps. One-way fill valve located on the bottom of the canister that allows fuel in, but not out, keeping the surge tank full. All pumps use check valves that prevent back-flow for multi-pump applications.
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.
Excess fuel in the surge tank simply overflows back into the fuel cell. The return from the pressure regulator is also routed to the surge tank canister to help keep it full.Īn integrated 1-way fill valve always keeps at least as much fuel in the surge tank as what is outside in the fuel cell. 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 2 liter surge tank. The opening must be on the top face of the fuel cell (i.e.
Radium fuel cell install#
To install a Radium Engineering FCST into a fuel cell, the following criteria must be met:ġ. The cell must have the industry standard 6"x10" 24-bolt flange opening.Ģ. It provides all the benefits of a traditonal 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.
Radium fuel cell professional#
It quickly became the preferred fuel system for professional racing. To simplify plumbing and packaging, in 2013 Radium Engineering introduced the first generation Fuel Cell Surge Tank (FCST) to the competition vehicle market. Since 2010, external Radium Engineering fuel surge tanks have been an excellent way to eliminate fuel starvation that occurs in racing.
