Radium FCST,Brushless Ti Automotive E5LM, Pumps Not Included

The Fuel Cell Surge Tank (FCST) is a drop-in 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 is NOT a glorified trap door box. 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. This product 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.

Integrated Surge Tank
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 a 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.

All variations of the FCST come standard with the following parts:
Radium 20-0146 Fuel Level Sensor Block-Off Kit
Radium 20-0435 Vent Valve, 12AN ORB to 8AN Male, Std Fill
Anodized Aluminum 6x10, 24-Bolt Fill Plate
Anodized Aluminum 2.2 Liter Surge Tank Canister
Anodized Aluminum Lift Pump Mounting Brackets
Anodized Aluminum Surge Tank Pump Cradle
Anodized Aluminum 6AN Male Return Fitting
Anodized Aluminum 8AN Male Feed Fitting
Stainless Steel Hardware and Viton O-rings
Insulated 10-32 Nuts for Electrical Studs
Electrical Crimp-on Ring Terminals

The 20-0693-00 Fuel Cell Surge Tank is only available without pumps included. However, Ti Automotive E5LM brushless fuel pumps can be purchased separately. The lift pump electrical and plumbing is set to be compatible with Walbro F90000267/274/285/295 fuel pumps. For dual brushless pump configurations, Radium recommends the Walbro F90000295 as a lift pump for maximum flow.
When ordering fuel pumps, make sure that each pump has a filter sock. However, there will be enough components included to use multiple surge tank pumps. Depending on the setup, some parts may not be used.
Ti Automotive brushless fuel pumps do not use an integrated check valve. Because the 2 surge tank pumps merge into a single outlet collector, these high flow 1-way valves permit multiple pumps to be staged.
The FCST also comes standard with a 2AN ORB plug in the "level switch" port.
