This comprehensive installation kit includes everything needed to install a Radium fuel surge tank with a single 39mm fuel pump in a 00-05 Honda S2000. To purchase the physical Radium Engineering FST, click HERE. The kit was not designed to work with the Radium MPFST. For our (fuel surge tank) FST install kit for the returnless fuel system found in the 06-09 Honda S2000, go HERE.
Here is a informative video on how a Radium Fuel Surge Tank works:
All Radium FSTs are CNC machined from aluminum and fully anodized and use PTFE insulated wiring, submersible hose, etc. to make them alcohol (ethanol/methanol/E85) compliant. The Honda S2000 install kit locates the FST in a hidden collision-safe area of the trunk behind the left seat using factory located threaded bosses. No modifications or drillling required. Because the S2000 is a small vehicle, please consider the decibels of the fuel pump selected. As shown below, 100% of the trunk space is still useable. 
The bolt-on aluminum bracket mounts to existing OEM holes and features 3 rubber isolation mounting points to reduce fuel pump noise and vibration.
Also included are wiring components with flying leads featuring Raychem solderless butt splices, and a weatherproof fuse and relay to drive the FST's fuel pump. Wiring is very simple and takes less than 30 minutes to assemble. No soldering is required. 
Included are 4 preassembled -6AN PTFE hoses which are great for all types of fuel including high alcohol contents, such as ethanol (E85).
