A 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 high quality -6AN PTFE Hose that draws fuel from the bottom of the FST.

Dual External Pumps, Horizontal FST
This FST is less than 5 inches tall which is ideal for many applications. The 2 fuel pump pickups are located at the bottom of the FST. The top port is used for the fuel return back to the main tank.
Dual External Pumps, Vertical FST
This FST includes PTFE pickup tubes that draw 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.
 
Optional 4-Port Fuel Pump Outlet Manifold:
When plumbing a single hose to the engine, Radium also offers a machined aluminum manifold that Tee's the fuel pump outlets together into a single AN fitting. However, since it is required to remove the pumps' check valves, this option should not be used if the two pumps will be staged. This optional fuel manifold is shown below using the vertical dual Bosch 044 FST. 
All required fittings are included, along with -8AN and -10AN outlet adapters. Shown below is the horizontal dual AEM 50-1005 FST with the 4-Port Manifold.
