Fuel Cell Surge Tank (FCST) by Radium Engineering

The Fuel Cell Surge Tank (FCST) is a fill plate replacement for popular fuel cells including Radium, ATL, FuelSafe, Pyrotect, Harmon, Jaz, etc. The FCST is designed for EFI vehicles experiencing fuel pump starvation issues while using a competition fuel cell. It features 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. Alcohol fuels such as E85, methanol, etc can be safely used.

The FCST uses the tried and true Radium Engineering fuel surge tank system preferred by professional motorsports teams worldwide. The optimized 2.2 liter canister supports 1, 2, or 3 internally mounted surge tank pumps capable of over 4000HP (Gas @ 3bar, BSFC .45).

The fuel pumps inside the surge tank provide the primary fueling to the engine. The "lift pump" mounts next to the surge tank canister and keeps the chamber filled. The volume of fuel inside the surge tank acts as a buffer always keeping the surge tank pump(s) supplied with fuel. This volume is also maintained by the "return" from the FPR. Excess fuel in the integrated surge tank bleeds out into the fuel cell without the need of expensive hoses and fittings. All of this is done inside the fuel cell with the FCST.

Because all of the compatible pumps utilize an integrated check valve, the FCST merges all pumps into a single outlet simplifying external plumbing. The return port has a tangential entry into the FST canister creating a swirl pot. This helps eliminate unwanted air bubbles and fuel foam that can affect fuel pump and engine performance.

The FCST uses high current stainless steel wiring terminals. 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.

The external fuel pump outlet port is signified by the "PUMP OUT" engraving. It is thread tapped with 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. The external "RETURN" port is used for low pressure fuel returning from the FPR. This port is tapped with 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. 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.

Please Note

  • If you are going to use your own pumps or source pumps elsewhere, select the option "Pumps Not Included" from the drop down. Some assembly is required. 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 may not be used. Compatible pumps are Walbro GSS342G3, Walbro F90000267/274/285, AEM 50-1200, AEM 50-1000.
  • A fuel cell is not included with the FCST. The fuel cell MUST use a 6x10, 24-bolt fill plate flange. The fuel cell cannot be any shorter than 8 inches. The distance from the top of the fuel cell to the bottom of the lift pump filter (lowest point of the kit) is adjustable from 8-9.5 inches.
