Radium Fst-R Ti Automotive E5Lm Pump Not Included

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 feeds 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 (lift) pump as well as the fuel returning from the fuel pressure regulator.

In the case of the FST-R, the regulator is built in to the surge tank and is recirculating fuel internally. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank.

Installing a surge tank is also an easy way to upgrade the fuel pump of a vehicle without opening or modifying the OEM fuel tank.

A fuel pressure gauge is needed in order to set and monitor fuel pressure and should be located along on the output line or at the fuel rail. The Radium universal fuel pressure gauge is perfect for this duty. Shown above is the gauge with the optional in-line Tee fitting.
