Radium Engineering  fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. The FST fuel pumps 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 upgade any standard fuel system with a compact size. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction. 

Both of these dual-pump configurations are ideal for high powered V or H configured engines with dual fuel rails. The anodized 6061 billet aluminum clamps and FST mount directly to the powder coated aluminum plate using stainless countersink bolts. Unlike others on the market, these clamps conductively transfer the fuel pumps thermal energy to the chassis increasing fuel pump longevity. Each pump has a dedicated vapor shield hose that draws fuel from the bottom of the FST.

Each pickup is dedicated to the respective external fuel pump. This enables all of the fittings to be secured to the top cap making for a nice compact plumbing package. 


When plumbing a single hose to the engine, Radium Engineering offers 20-0063. This is a machined aluminum 4-port manifold (shown below) that merges the fuel pump outlets together into a single AN fitting. All required fittings are included, along with -8AN and -10AN outlet adapters.

There is also 20-0463 which retains the Bosch check valves (see picture above). This is necessary if the two fuel pumps will be staged.
