New! Radium-spec Fuel Cells Now Available! See information at bottom of page.
The Fuel Cell Surge Tank (FCST) is a fill plate replacement for popular fuel cells including ATL, FuelSafe, Pyrotect, Harmon, Jaz, etc. The FCST is designed for EFI vehicles experiencing fuel pump starvation issues while using a competition fuel cell.Â The FCST is NOT a glorified trap door box. It is the first of its kind to feature a true dual-chamber fuel tank utilizing a single lift pump and up to three surge tank pumps, all in a compact drop-in package.
The FCST also provides a quick and easy way to drop-in an upgraded fuel pump system for extra flow for vehicles with large power demand upgrades such as forced induction.Â Alcohol fuels such as E85, methanol, etc can be safely used.Â
The surge tank incorporates a multi-pin high amperage sealed electrical bulkhead connector that has 1 connector for each of the 3 selectable pumps. All internal wires are gasoline, ethanol, and methanol compliant. Furthermore, the internal tube and hoses are a special fluoroelastomer formulation that is suitable for submersion in all types of fuel.

Selecting the FCSTâ€™s Fuel Pump
The FCST is available with or without fuel pumps. Radium assumes that the lift pump and the surge tank pumps will be the same brand so the internal wiring connectors for the surge tank pumps and the lift pumps will always be the same.Â
If you are going to use your own pumps or source pumps elsewhere, select the option â€œSurge Tank Pumps and Lift Pump Not Includedâ€ from the drop down.Â Note that there will be enough components included with this option to use 1, 2, or 3 surge tank pumps. Depending on the setup, some parts will simply not be used. Next, select the type of pumps that will be used so the appropriate internal wiring connectors will be included in the kit.Â
If pumps are needed, the FCST will come preassembled and sock filters will be installed on all fuel pumps. First, select the preferred number of surge tank pumps that will be used from the pull down menu. The FCST is sold in 1, 2, or 3 surge tank pump configurations with 1 lift pump. Next, select theÂ type of pumps that will be used so the appropriate internal wiring connectors will be included in the kit.Â Note that the surge tank pumpâ€™s wiring harness is always configured to use up to 3 pumps even if only 1 surge tank pump is selected.
FCST Fittings Explained
The anodized green fittings signify the surge tank fuel pump outlets to the engine. These are available in -6AN male only.Â If only 1 surge tank pump is used, the â€œPUMP2â€ and â€œPUMP3â€ ports are plugged using the included anodized aluminum port plugs. If 2 surge tank pumps are used, the â€œPUMP3â€ port is plugged using the included anodized aluminum port plug.Â If 3 surge tank pumps are used, the included anodized aluminum port plugs will not be used.
The â€œRETURNâ€ black port fitting is used for low pressure fuel returning from the fuel pressure regulator. This port is tapped with 3/4â€³-16 threads and a -6AN male fitting is included. However, larger -8AN or -10AN male port adapter fittings can be purchased separatelyÂ HEREÂ if required.
FCST Parts Required
A fuel cell is not included in the FCST kit. However, a Radium fuel cell can be added to the order (see below for more information). The fuel cell MUST use a 6Ã—10, 24-bolt fill plate flange. The fuel cell cannot be any shorter than 8 inches.Â The distance from the top of the fuel cell to the bottom of the lift pump filter (lowest point of the kit) is adjustable (8-11 inches depending on how the lift pump is mounted). If the fuel cell is deeper than 11 inches, use thisÂ Radium Fuel Pump Inlet AdapterÂ to relocate the lift pump filter to the bottom of the fuel cell. For the ultimate in fuel starvation protection, the lift pump or pickup filter can be placed into theÂ Radium Collector Box.
The FCST uses a 3/4â€³ (19mm) vent hole. If you dont currently have a roll over protection fitting, thisÂ Radium -8AN Vent ValveÂ can be used.
If you do not currently have a 6-bolt (2.18â€³ B.C.) filler, thisÂ Radium Fill NeckÂ is unique in that it can be used for direct filling or remote filling.
Radium Fuel Cells
Radium Engineering has teamed up withÂ Fuel SafeÂ to offer a full line of Radium FCST-equipped fuel cells. These Radium-spec fuel cells are available with a choice of 4 different bladder typesÂ in many popular sizes. All Radium fuel cells featureÂ a lightweight corrosion-resistant black powder-coated aluminum can which is an upgrade over the standard mild steel cans of the past. Anti-slosh foam is included inside the bladder to reduce sloshing and optimize the fuel collection of the lift pump. The fuel cells are delivered fully assembled with the FCST of your choice installed. All fuel cells are manufactured in the USA.
