Radium Fuel Surge Tank Install Kit — Honda S2000 AP1 1999-2004

This comprehensive installation kit includes everything needed to install a Radium Fuel Surge Tank with a single 39mm fuel pump in a 1999-2004 Honda S2000 AP1. The FST surge tank is sold separately — this kit is not designed to work with the Radium MPFST.

All Radium FSTs are CNC-machined from aluminium, fully anodized, and use PTFE-insulated wiring and submersible hose to ensure full alcohol compliance (E85, ethanol, methanol). The kit locates the FST in a hidden, collision-safe area of the trunk behind the left seat using factory threaded bosses — no modifications or drilling required. 100% of trunk space remains usable.

The powder-coated aluminium bracket mounts to existing OEM holes and features three rubber isolation points to reduce fuel pump noise and vibration. Wiring components include flying leads with Raychem solderless butt splices and a weatherproof fuse and relay — no soldering required, assembly takes under 30 minutes.

Four pre-assembled -6AN PTFE hoses are included, fully compatible with high-alcohol fuels including E85, ethanol, and methanol. PTFE is non-permeable, eliminating fuel vapour smell, with anodized aluminium hose ends and an inner stainless steel braid covered in black PVC for abrasion and debris protection.
