Over the years, Radium Engineering has continued to refine the FCST into a robust and highly functional piece of hardware.
-Merged single 10AN ORB female threaded outlet. All pumps use check valves that prevent back-flow in multi-pump applications.
-One-way fill valves located on the bottom of the canister that allows fuel in, but not out, keeping the surge tank full.
-Multiple fuel pump options including gerotor, turbine, and brushless DC motor pumps.
-Hermetically sealed high-current stainless steel electrical studs capable of handling all pumps.
-Simplified servicing features eliminating nylon sealing washers and fuel cell retaining brackets.
-Full CNC aluminum construction with anodized surfacing for superior corrosion resistance.
-Fuel compatibility: leaded and unleaded gasoline, methanol, ethanol, E85, etc.
-Dynamic safety vent valve with rollover protection and fuel fill shut-off protection.
-Optional fuel surge tank level switch and diagnostic LED failsafe port (shown below).
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.
WHATS IN THE BOX?
The following comes standard with every FCST variation configured per part number
-8AN DSV (dynamic safety vent) valve
-6x10 24-hole FKM gasket
-6AN male return fitting (other sizes must be purchased separately)
-8AN male pump out fitting (other sizes must be purchased separately)
-Fuel level sensor block-off plate
-Fuel level switch block-off plug
-Three FKM 1-way fill valves
-Stainless steel mounting hardware
-Insulated anodized aluminum acorn nuts
-Electrical power wire ring terminals
-Links for compatible fillers (not included), Direct Mount or Remote Mount.
20-099X-XX FCST
The 20-099X-XX Fuel Cell Surge Tanks utilize new design features that reduce overall weight by 35.3%. These new additions also improve assembly time. They also use stronger stainless steel lift pump mounting brackets. Furthermore, they are compatible with Radium Engineering's shrouded fuel level sensors.
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
The fuel filler pattern uses an industry standard 6-bolt (2.18" B.C.) flange. 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. For compatible vent kits and more information on how these are plumbed and routed,
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 HERE.
FUEL LEVEL SWITCH / DIAGNOSTIC INDICATOR
These new FCSTs come standard with a 2AN ORB plug preinstalled in the "level switch" port. For information on adding a fuel level switch and diagnostic indicator, click HERE. This little device provides a warning when the fuel level inside surge tank canister drops by 20% or more.
