Since 2010, external Radium Engineering fuel surge tanks have been an excellent way to eliminate fuel starvation that occurs in racing. To simplify plumbing and packaging, in 2013 Radium Engineering introduced the first generation Fuel Cell Surge Tank (FCST) to the competition vehicle market. It quickly became the preferred fuel system for professional racing.
WHAT IS A FCST?
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 utilizing a single lift pump and up to 3 surge tank pumps all packaged inside the fuel cell. It provides all the benefits of a traditonal external fuel surge tank without safety concerns and plumbing complexity.
IS THIS COMPATIBLE WITH MY FUEL CELL?
To install a Radium Engineering FCST into a fuel cell, the following criteria must be met:
1. The cell must have the industry standard 6"x10" 24-bolt flange opening.
2. The opening must be on the top face of the fuel cell (i.e. not a side face).
3. The cell depth must be at least 7.7" (196mm) measured from the outer top face to the internal bottom face.
HOW IT WORKS
A lift pump scavenges fuel from the bottom of the fuel cell and pumps it into the 2 liter surge tank. Inside the surge tank canister, up to 3 EFI fuel pumps can be used to feed high pressure fuel to the engine. 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. The return from the pressure regulator is also routed to the surge tank canister to help keep it full.
An integrated 1-way fill valve always keeps at least as much fuel in the surge tank as what is outside in the fuel cell. Excess fuel in the surge tank simply overflows back into the fuel cell. This dynamic sequence is all done inside the safety of a fuel cell.
The different FCST part numbers are based on the brand and quantity of fuel pumps.
The 20-069X-XX Fuel Cell Surge Tanks (with exception to brushless E5LM) are available with and without pumps included. The lift pump is always matched to be the same style pump(s) found inside the fuel surge tank canister. Any option that lists "Pump Included" comes pre-assembled with new fuel pumps and filters installed.
If "pumps not included" is ordered fuel pumps must be sourced separately. A filter sock will only be required for the lift pump as inlet filters are already supplied for the surge tank pumps. Also, there will be enough components included with this option to use up to 3 pumps in the surge tank. Depending on the setup, some parts may not be used.
STANDARD FITTINGS
PUMP OUT -8AN MALE
The external fuel pump outlet port is signified by the "PUMP OUT" engraving. It uses 7/8"-14 threads making it compatible with all 10AN ORB fittings. The FCST comes standard with a common 10AN ORB to 8AN male adapter fitting. However, various 10AN ORB adapter fittings can be purchased separately.
RETURN -6AN MALE
The external "RETURN" port is used for low pressure fuel returning from the FPR. This port uses 3/4"-16 threads making it compatible with all 8AN ORB fittings. The FCST comes standard with a common 8AN ORB to 6AN male adapter fitting. However, various 8AN ORB adapter fittings can be purchased separately.
VENT -8AN MALE
The external "VENT" port is tapped with 1-1/16"-12 threads making it compatible with all 12AN ORB fittings. The FCST comes standard with 20-0435 which uses a common 8AN male outlet fitting for standard fuel filling. However, 20-0462 can be purchased separately with a 12AN male fitting for quick fill dry break systems that require a high-flow vent.
WHAT ELSE IS NEEDED?
FUEL CELL
A fuel cell is not included with the FCST. The fuel cell MUST use a 6x10, 24-bolt fill plate flange. The distance from the outer top face to the internal botton face must be at least 7.7" (196mm). The distance from the top of the fuel cell to the bottom of the lift pump filter (lowest point of the kit) is adjustable. However, if the fuel cell is deeper than 10 inches, purchase this Lift Pump Extension.
FUEL FILLER
If you do not currently have a 6-bolt (2.18" B.C.) filler, Radium Engineering has them for both direct filling and remote filling.
VENT HOSE
A hose and/or filter must be connected to the "VENT" port fitting.
