This comprehensive installation kit includes everything needed to install a Radium fuel surge tank with a single 39mm fuel pump in a Mitsubishi Lancer Evolution 8-9. To purchase the physical Radium Engineering FST, click HERE. The kit was not designed to work with the Radium MPFST.
Here is a informative video on how a Radium Fuel Surge Tank (FST) works:
All Radium FSTs are CNC machined from aluminum. They are fully anodized and use PTFE insulated wiring, submersible hose, etc. to make them alcohol (ethanol/methanol/E85) compliant. The Mitsubishi Evolution 8-9 install kit locates the FST in a collision-safe area of the trunk, centered behind the rear seat (shown below without carpet installed).
This allows for the majority of the trunk space to still be useable. The aluminum bracket solidly mounts to the V-brace in front of the rear seat carpet cover in the trunk. The FST with black anodized bracket is isolated through the OEM carpet cover (shown below) 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 four -6AN PTFE hoses which are cut to length and preassembled.

NOTES
Lastly, due to the restrictive return port on the OEM fuel pump housing, a slightly higher static fuel pressure is normal when using a high flow pump. To alleviate this issue, the OEM venturi jet pump in the return port can be modified to alleviate the restriction and promote fuel flow back into the OEM fuel tank. This is noted in the instruction manual.
