Radium Engineering Fuel Surge Tank Install Kit for Mitsubishi EVO VIII | IX (2003-2007)

Looking to enhance your Mitsubishi EVO's fuel system? The Radium Engineering Fuel Surge Tank Install Kit is designed specifically for the EVO VIII and IX models from 2003 to 2007. This kit comes with everything you need to seamlessly install a Radium Engineering single pump, ensuring you have a reliable and efficient fuel delivery system.

Quality You Can Trust

Crafted from CNC-machined aluminum, all Radium Fuel Surge Tanks (FSTs) are fully anodized and equipped with PTFE insulated wiring and submersible hoses. This makes them compliant with alcohol fuels like ethanol, methanol, and E85, so you can rest easy knowing your setup is robust and reliable.

Smart Design for Your Trunk

The installation kit is thoughtfully designed to position the FST in a collision-safe area of the trunk, right behind the rear seat. This clever placement allows you to keep most of your trunk space usable, so you won’t have to sacrifice practicality for performance. The included nickel-plated aluminum bracket mounts securely to the V-brace in front of the rear seat carpet cover, ensuring stability while minimizing noise and vibration thanks to the OEM carpet cover.

Simplified Wiring and Assembly

Wiring your new fuel surge tank is a breeze! The kit includes all necessary components, featuring flying leads with a weatherproof fuse and relay to power the fuel pump. You won’t need to worry about complex soldering; everything can be assembled in under 30 minutes!

Durable PTFE Hoses

Included in the kit are four preassembled PTFE hoses, cut to length specifically for your EVO. PTFE is the ideal choice for high-alcohol fuels, as it’s non-permeable and eliminates any unpleasant fuel vapor smells inside your vehicle. The hoses feature anodized aluminum hose ends and a stainless steel braid that can withstand extreme fuel pressures, all wrapped in black PVC for added protection against debris and abrasion. The supplied hoses are in -6AN size and integrate smoothly with your stock fuel lines without completely replacing them.

Additional Notes

• If you need a Radium Engineering dual internal pump FST, you can achieve this by selecting a dual pump FST. Keep in mind that the plumbing and electrical components in this kit are designed for a single pump setup. You’ll also want to grab a DIY harness for the additional pump and plumb a second hose from the FST to the fuel rail.
• For those considering a Radium FST-R, this kit allows you to reuse the OEM Mitsubishi Fuel Pressure Regulator (FPR). One hose in the kit will be unused, and you'll need to either remove, drain, or plug the OEM 1/4" rubber FPR return hose. Don’t forget to extend the FPR vacuum hose to reach the trunk!
• For more specific details on the above scenarios, feel free to reach out to us!
• Be aware that using a high-flow pump may result in slightly higher static fuel pressure due to the restrictive return port on the OEM fuel pump housing. Modifying (enlarging) this return port can help alleviate the restriction and improve fuel flow back into the tank, as noted in the instruction manual.
