This comprehensive installation kit includes everything needed to install a Radium Engineering single pump Walbro, AEM, Aeromotive, Deatchwerks, or Bosch equipped fuel surge tank (FST) in a Mitsubishi Lancer Evolution X.

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 X install kit locates the FST in a collision-safe area, centered behind the rear seat but in front of the plastic paneling in the trunk (shown below).


This allows 100% of useable trunk space as the panel goes back on after the install. The powder coated aluminum bracket secures to OEM mounting bosses so no drilling or cutting is necessary. Furthermore, the OEM battery and windshield washer fluid bottle are retained and do not need to be relocated.

Also included are wiring components with flying leads featuring 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 4 PTFE hoses which are cut to length and preassembled. PTFE hose is perfect for all types of fuel, especially with high alcohol contents, such as ethanol (E85). Unlike standard rubber hose, PTFE is non-permeable and eliminates any possible fuel vapor smell in the vehicle. Radium PTFE hoses use anodized aluminum hose ends and are cut-to-length specifically for this application. The inner stainless steel braid resists extreme fuel pressures and is covered with black PVC which gives the hose added protection from debris and provides abrasion protection. Supplied in -6AN size only.
