Radium Engineering Fuel Surge Tank Install Kit, EVO X

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 X. The kit was NOT designed to work with the Radium MPFST or RHD EVOX models that use the large OEM windshield washer reservoir (check your reservoir before ordering). 



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 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 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.

The suppled -6AN hoses integrate with the OEM fuel lines.
 

EVO X Install Kit Features:

-Preassembled 3/8" (-6AN) PTFE Hoses 
-Aluminum Mounting Bracket
-AN and OEM Style Adapter Fittings
-Stainless Steel Hardware 
-Wiring Components with Relay and Fuse 

NOTES:  

If a Radium FST-R is required, this can be achieved. However, the plumbing in this kit was designed to reuse the OEM Mitsubishi FPR. One of the hoses in this kit will not be used and the OEM 1/4" rubber FPR return hose will need to be either removed, drained, or plugged. Furthermore, the FPR vacuum hose will need to be extended to the trunk.
Neither of the two scenarios above are covered in depth in the instruction manual. Contact us for more details.

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 fuel pump housing return port can be modified (enlarged) to alleviate the restriction and promote fuel flow back into the OEM fuel tank. This is noted in the instruction manual.
