Radium Engineering Fuel Surge Tank Kit | 2000-2005 Honda S2000 (20-0094)

An S2000 on slicks generates exactly the lateral G its fuel tank was never baffled for.

The Radium Engineering Fuel Surge Tank Install Kit for the 2000-2005 Honda S2000 is the comprehensive, chassis-specific answer: everything needed to install a Radium fuel surge tank with a single 39mm fuel pump in the AP1, locating the FST in a hidden, collision-safe area of the trunk behind the left seat using factory located threaded bosses. No modifications or drilling required, and 100 percent of the trunk space remains usable. The bolt-on aluminum bracket mounts to existing OEM holes with 3 rubber isolation points reducing fuel pump noise and vibration, a detail that matters enormously in a car this small. FST and pump sold separately.

What You'll Feel

• Fuel starvation eliminated through sustained cornering on a chassis built for exactly that
• The whole trunk still yours, with the FST hidden behind the left seat area
• Pump noise civilized by the triple rubber isolation mounts, in a cabin where every decibel counts
• A collision-safe mounting location chosen by engineers, not convenience
• Zero drilling, with every fastener landing in factory threaded bosses

The Details

Radium's S2000 kit answers the questions surge tank installs usually leave open. Location: behind the left seat in the trunk, protected in a collision and invisible in daily use. Plumbing: AN and OEM adapter fittings plus PTFE hose resistant to ethanol, methanol, and E85, connecting the FST into the factory fuel system. Noise: the isolation mounts exist because the S2000 is a small car and pump drone travels, and Radium's own advice is to consider the decibel character of the pump you select. The kit pairs with Radium's single 39mm FST bodies and explicitly not the MPFST, so choose the surge tank accordingly. Wiring completes with a Radium DIY wiring kit for the surge pump.
