This comprehensive installation kit includes everything needed to install a Radium Fuel Surge Tank (FST) with a single 39mm fuel pump in a 2000-2005 Honda S2000. (Click here for the install kit for the returnless fuel system found in the 2006-09 Honda S2000.)

All Radium FST 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).


  • Preassembled 3/8" (-6AN) PTFE Hoses
  • Aluminum Mounting Bracket with Vibration Isolators
  • AN and OEM Style Adapter Fittings
  • Stainless Steel Hardware
  • Wiring Components with Relay and Fuse
