Radium Engineering Pumpless Single 10AN Center Pick-Up High Volume Fuel Surge Tank
A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. The FST fuel pump(s) feed the fuel rail(s). The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump 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 upgrade any standard fuel system. This is an excellent fuelling solution for vehicles installing large demand power upgrades such as forced induction.

High Volume Fuel Surge tank
Radium Engineering 20-0081 high volume fuel surge tank (HVFST) was designed for users that already have a secondary external fuel pump. It is ideal for high flow external fuel pumps requiring a large reservoir and feed line. It features a large 2.21L (0.58 gallon) canister and a 5/8" (10AN) single pick-up tube.
A "lift pump" is required to supply fuel to the HVFST. Excess fuel is then routed back to the main tank (or fuel cell). The pump feeding the engine, draws fuel from the surge tank, with excess returning from the fuel pressure regulator back to the surge tank.
The 3 black ports are used for fuel entering and exiting the surge tank. These ports are tapped to 3/4-16 (8AN ORB) and three -6AN male adapter fittings are provided.
Radium does not recommend mounting this surge tank horizontally, as the pick-up may be prone to drawing in air pockets.
