How does a RADIUM Fuel Surge Tank work?
Radium Fuel Surge Tank install |Evo 8
The FST sits in a collision-safe area of the boot, centred behind the rear seat, on a black anodised aluminium bracket that bolts to the OEM V-brace. Most of the boot remains usable and the tank is isolated behind the OEM carpet trim to reduce pump noise and vibration. Pre-assembled -6AN PTFE hoses with stainless braid and black PVC coating are non-permeable, preventing fuel odour in the cabin.
Note: Suits Radium FSTs using a single 39mm fuel pump; not designed for the Radium MPFST. Because the OEM pump housing has a restrictive return port, static fuel pressure may rise slightly with a high-flow pump – this can be addressed by modifying the venturi jet pump in the OEM return line as described in the instructions. Installation by a professional is recommended.
