FCST-X, FUEL CELL SURGE TANK
OVERVIEW
Ordering a fuel cell complete with FCST-X, filler, vent and level sender can be complex and requires several parts to be ordered. In order to make sure you order the correct parts that work together, click the banner below to use our configurator tool. This will ask you questions step-by-step to help you get each choice and at the end will allow you to add all of the items to your cart to see pricing and make your purchase.
HISTORY OF THE FCST
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, Radium Engineering introduced the first to market Fuel Cell Surge Tank (FCST) in 2013. This FCST quickly became the preferred fuel system for the competition vehicle market and professional racing. After 10 years of kaizen, the transformation brings the release of the FCST-X (Fuel Cell Surge Tank-10 Years).
HOW IT WORKS
A lift pump scavenges fuel from the bottom of the fuel cell and pumps it into the 2L surge tank. Inside the surge tank canister, up to 3 EFI fuel pumps can be used to feed high pressure fuel to the engine. As shown below, fuel cannot pass between the 3 independent filtration chambers (A, B, C). If less than 3 pumps are installed, the empty port does NOT need to blocked off.
If the lift pump starves, the volume inside the surge tank canister will keep the surge tank pumps fed and the engine supplied with fuel. The return from the fuel pressure regulator is also routed to the surge tank canister to help keep it full.
There are 3 fill valves integrated to the bottom of the surge tank. These 1-way FKM fill valves are sealed shut unless the fuel level in the cell rises above the fuel level in the surge tank. If this happens, each fill valve opens and sends 355LPH of fuel (1065LPH total) into the surge tank until fuel level reaches an equilibrium.
Excess fuel in the surge tank simply overflows back into the fuel cell. This dynamic sequence is all done inside the safety of a fuel cell.
