Radium FCST Fuel Cell Surge Tank Suit External Pumps - No Pumps Included
Note: 10 and 14 Gallon fuel cells will require lift pump extension bracket 20-0214
BACKGROUND
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:
- The cell must have the industry standard 6"x10" 24-bolt flange opening.
- The opening must be on the top face of the fuel cell (i.e. not a side face).
- The cell depth must be at least 7.7" (196mm) measured from the outer top face to the internal bottom face.
The 20-0695-00 Fuel Cell Surge Tank is only available without pumps not included. It is designed to be used with a mechanical fuel pump or inline electric pump(s). One or two -10AN (5/8") fuel pickups are used inside the surge tank. Each pickup uses a 80u (micron) filter. If two pickups are used, 20-0737 Distribution Block is recommended for pumps that use a 12AN inlet.
The lift pump electrical and plumbing for this kit is set to be compatible with Walbro F90000267/274/285/295 fuel pumps. Radium Engineering recommends the Walbro F90000295 as a lift pump for maximum flow with a 14-0143 Filter Sock.
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, 20-0535 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.
OPTIONAL ACCESSORIES
FUEL LEVEL SENDER
The FCST comes standard with a fuel level sender block off plate. However, SAE fuel level senders of various lengths can be purchased separately.
FUEL LEVEL SWITCH / DIAGNOSTIC INDICATOR
The 20-069X-XX FCST comes standard with a 2AN ORB plug in the "level switch" port. This little device provides a warning when the fuel level inside surge tank canister drops by 20% or more.
