Radium Engineering Fuel Surge Tank Install Kit for Mitsubishi EVO X (2008-2014)

If you're looking to upgrade your Mitsubishi EVO X with a reliable fuel surge tank, the Radium Engineering Fuel Surge Tank Install Kit is just what you need. This kit has everything you require to seamlessly install a Radium Engineering single pump, making it a fantastic addition to your vehicle.

Quality You Can Trust

All Radium Fuel Surge Tanks (FSTs) are expertly CNC machined from high-quality aluminum and come fully anodized. The kit features PTFE insulated wiring and submersible hose, ensuring it meets the demands of alcohol fuels like ethanol, methanol, and E85. When installed, the FST is cleverly positioned in a collision-safe zone, right behind the rear seat yet in front of the trunk's plastic paneling. This thoughtful design means you can retain 100% of your usable trunk space, as the panel fits back perfectly after installation.

Easy Installation

The kit includes a powder-coated aluminum bracket that secures to OEM mounting points, meaning no drilling or cutting is necessary. Plus, you won't have to relocate the OEM battery or windshield washer fluid bottle, making the process even smoother.

Simple Wiring and Preassembled Hoses

Wiring is a breeze with the included components, featuring flying leads, a weatherproof fuse, and a relay to power the fuel pump. You can have everything wired up in less than 30 minutes—no soldering required!

You'll also receive four PTFE hoses that are preassembled and cut to length, specifically designed for this application. PTFE hoses are ideal for handling all types of fuel, especially those with high alcohol content. Unlike standard rubber hoses, PTFE is non-permeable, which means you won't have to worry about any fuel vapor smells inside your vehicle. The hoses come with anodized aluminum hose ends and are reinforced with a stainless steel braid, ensuring they can withstand extreme fuel pressures. They are supplied in a -6AN size and integrate seamlessly with your stock fuel lines without completely replacing them.

Key Features

• Preassembled 3/8" (-6AN) PTFE Hoses
• Powder Coated Mounting Bracket with Vibration Isolators
• AN and OEM Style Adapter Fittings
• Stainless Steel Hardware
• Installation Instructions

Fitment

• Mitsubishi EVO X 2008-2014

Important Notes

• Pressure should remain around 47.5 psi for optimal performance.
• If you're considering a Radium Engineering dual internal pump FST, this kit can accommodate that. Just remember that the plumbing and electrical components are designed for a single pump, so you'll need to select a dual pump FST and a DIY harness for the additional pump.
• For those needing a Radium FST-R, this kit is compatible but designed to reuse the OEM Mitsubishi fuel pressure regulator (FPR). One hose in the kit won't be used, and you'll need to either remove or plug the OEM 1/4" rubber FPR return hose. The FPR vacuum hose will also need to be extended to the trunk. These scenarios aren't covered in depth in the instruction manual, so feel free to reach out for more details.
• Due to the restrictive return port on the OEM fuel pump housing, a slightly higher static fuel pressure is normal with a high-flow pump. To improve fuel flow back into the OEM fuel tank, you may want to modify (enlarge) the return port.
