Radium Engineering 20-1195 features a large 2.21L (0.58 gallon) canister. A combination of 3 different fuel pickups can be used. There are two 80u (micron) filters included for the two 10AN (5/8") pickups.
The FST fuel pump(s) directly feed the engine. The volume of fuel inside the surge tank acts as a buffer to always keep the FST supplied with fuel. This volume is maintained by the main fuel tank's pump as well as the fuel returning from the fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. The surge tank also provides a quick and easy way to upgade any standard fuel system. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction.
