Radium Engineering Fuel Surge Tank Install Kit (FST Not Incl) for Honda S2000 AP1 1999-2004

Radium Fuel Surge Tank Install Kit (FST Not Incl) - Honda S2000 AP1 99-04

Application: Honda S2000 (2000-2005)
Part Type: Fuel surge tank install kit (FST not included)
Part Number: 20-0094

This Radium kit includes everything needed to install a Radium fuel surge tank (FST) with a single 39mm fuel pump in a 2000-2005 Honda S2000. Radium FSTs are CNC-machined, anodised aluminium with PTFE-insulated wiring and submersible hose for full alcohol fuel compatibility (E85, ethanol, methanol).

The FST mounts in a hidden, collision-safe area of the boot behind the left seat using the factory threaded bosses – no drilling or modification is required and 100% of the boot space remains usable. The aluminium bracket bolts to existing OEM holes with three rubber isolation mounts to reduce pump noise and vibration, and the wiring uses flying leads with Raychem solderless butt splices plus a weatherproof fuse and relay, assembling in under 30 minutes.

Key Features

• Hidden Mounting: Behind the left seat using factory threaded bosses – no drilling
• Isolated Bracket: Three rubber isolation mounts reduce pump noise and vibration
• PTFE Hoses: Four pre-assembled 6AN PTFE hoses, alcohol fuel compatible
• Solderless Wiring: Raychem solderless splices, weatherproof fuse and relay

What's Included

• 4x Pre-assembled 3/8" (6AN) PTFE hoses
• 1x Aluminium mounting bracket with vibration isolators
• AN and OEM-style adapter fittings
• Stainless steel hardware
• Wiring components with relay and fuse

Important Notes

• Fuel surge tank and fuel pump are NOT included – both are sold separately
• Not designed for the Radium MPFST
• The main tank pump must keep the surge tank full – as a guide it should flow roughly 40–50% of the surge tank pump's flow, so a main tank pump upgrade may be required
• The S2000 is a small car, so consider pump noise when choosing a surge tank pump
• For the 2006-2009 S2000 (returnless fuel system) use the 20-0114 kit
• Installation instructions are available in the Instructions tab
