Fuel Rails & Regulators

This comprehensive installation kit includes everything needed to install a Radium fuel surge tank with a single 39mm fuel pump in a 06-09 Honda S2000. The kit was not designed to work with the Radium MPFST.

This FST install kit utilizes Radium's innovative FST-R surge tank (sold separately) which incorporates an integrated fuel pressure regulator designed for the returnless fuel system found in the 06-09 S2000. This eliminates the need for an external FPR to be purchased. Furthermore, leaving the FST-R regulator barb disconnected to manifold pressure will emulate the OEM fuel pressure, if required.

Also, the 06-09 S2000 has no low pressure fuel return hose that plumbs back into the fuel tank. Included in this kit is a billet barb adapter that routes the excess fuel from the FST back into the main fuel tank through the fuel filler hose.

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 powdercoated 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). Unlike standard rubber hose, PTFE is non-permeable and eliminates any possible fuel vapor smell. These PTFE hoses use anodized aluminum hose ends and are cut-to-length specifically for the 06-09 S2000 application. The inner stainless steel braid resists extreme fuel pressures and is covered with black PVC which gives the hose added protection from debris and provides abrasion protection.

This big bore fuel rail features a large 0.69" diameter internal bore with three -8AN O-ring ports (3/4"-16 female threads) to accept a variety of adapter fittings for custom high flow fuel system builds. The fuel rail is machined, anodized, and laser etched for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85.

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.
