    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 upgade any standard fuel system without the need to modify the stock fuel tank or pump. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction. 

    All RADIUM Fuel Surge Tanks Include:

    -Extruded and Machined 6061 Aluminum 1.5 Liter Canister 
    -Removeable O-Ring Sealed Billet 6061 Aluminum Caps  
    -Anodized and Laser Engraved  
    -Nickel plated metal electrical connector
    -6AN Feed and Return Fittings 
    -Stainless Steel Hardware 
    -Factory Pressure Tested Before Shipment
    -Lifetime warranty on all Radium Components (excludes fuel pump, hoses and fittings)

    Radium Walbro 400 and 400/E85 equipped Fuel Surge Tank

    The Walbro 400 FST The Walbro 39/50 DCSS 400lph High Performance fuel pump (P/N F90000262) is the highest flowing internal pump available on the market today. Official flow data for this pump is available HERE. The pump mounts internally using an anodized laser cut bracket. The FST also incorporates a nickel plated quick disconnect sealed electrical connector. All internal wires are PTFE coated to resist gasoline, ethanol, and methanol corrosion. The internal hose is a special fluoroelastomer formulation that resist permeation internally and externally and is submersible in all types of fuel. This cost efficient compact design can support ~1025bhp @ 3Bar Pressure/.67 BSFC. This number will be approximately 20% lower for forced induction. See below for E85 version.

    RADIUM Single Walbro 400/E85 FST The Walbro 39/50 DCSS High Performance fuel pump (p/n F90000267) is specifically designed for use with E85 fuel and flows about 6% more than the gasoline version. This pump was designed to use any mixture combination of ethanol and gasoline (0-100%). It features the same technology of the 39/50 DCSS pump but modified for better compatibility with the corrosive ingredients in E85.  Official flow data for this pump is available HERE. The pump mounts internally using an anodized laser cut bracket. The FST also incorporates a nickel plated quick disconnect sealed electrical connector. All internal wires are PTFE coated to resist gasoline, ethanol, and methanol corrosion. The internal hose is a special fluoroelastomer formulation that resist permeation internally and externally and is submersible in all types of fuel.  This cost efficient compact design can support ~1025bhp (or 825bhp on E85) @ 3Bar Pressure/.67 BSFC. This number will be approximately 20% lower for forced induction.

    Only one Walbro 400 style pump fits inside this fuel surge tank.

    OPTIONAL MOUNTING BRACKETS:

    The fuel surge tank can be mounted near the main fuel tank or in the engine bay. Mounting locations near heat sources or moving parts such as suspension components should be avoided. It should also be mounted away from common collision areas. Choose a bracket below that best fits your mounting needs.

    Floor and Wall Mount - This bracket is laser cut from aluminum and powder coated black and can be mounted on the side or bottom of the surge tank.

    Frame Mount - Because this bracket has a 90deg formed bend and is cantilevered, it is constructed from steel for superior strength. It is not only nickel plated to resist corrosion, it also allows for components to be grounded to the spare hole in the bracket. This assumes the bracket is mounted to an electrically conductive material such as a steel frame.

    Angled Mount - This mounting bracket is used for vehicles that may have a limited mounting height. It can be mounted on a floor and against a wall. This bracket is made from laser cut aluminum and powder coated black.

    OPTIONAL WIRING HARNESS

    A universal fully populated wiring harness is available for an additional cost. This simplifies the wiring during installation. Please see details of the harness HERE.
