FUEL SURGE TANK KIT, EVO X, FST SOLD SEPARATELYThis 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.

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.

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 Engineering dual internal pump FST is required, this can be achieved. However, the plumbing and electrical in this kit was designed for 1 pump. Simply choose a FST with dual pumps to use with this EVO install kit. Also pickup a DIY harness as well for the electrical required to drive the second FST pump. Lastly, you will need to plumb a second hose from the FST to the fuel rail. These PTFE hoses can be helpful.

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.

That wasn’t too big or bulky looking on my bathroom wall.
It was a perfect fit for my bathroom, cabinet hanging over the toilet.

Easy to assemble and install
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
This cabinet meets our need for more bathrooms storage without interfering with the space in our smallish bathroom. The package arrived well packed in cardboard with foam inserts to protect the parts from damage in transit. I was able to easily follow the included directions with minimal fuss. In several cases, extra hardware piece were included, which I really appreciated. The quality of the construction was excellent. The only this that concerned me was the weight bearing capability of the included shelves. I added a few liquid or lotion filled bottles and noticed the shelves sagging, so I may have to cut my own shelves to better support. The cabinet looks great and is exactly as pictured in the listing after I assembled it. The ability to customize the shelves is also helpful. I looked at several cabinets for this purpose, some more expensive, some less, and I am happy with the money spent for this cabinet.

Great bathroom cabinet!
Color: White, Style: Wall Cabinet
My husband mounted this cabinet over our toilet and it’s the perfect addition! It looks great, matches the cabinets we already have and adds much needed storage! I plan on buying a second to put in my daughter’s/ the guest bathroom. The doors are magnetic and close securely, and the shelves are adjustable and feel sturdy. It was very easy to put together and feels very secure mounted on the wall

Mounting process could have been easier but still a beautiful cabinet
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Beautiful cabinet seems to be good quality I just keep admiring something so beautiful about the white. The extra hardware is thoughtful. With some master skills I was able to get it mounted perfect. It was not a breeze but nonetheless I always find a way. I found the best way to mount this was to hold it against the wall and follow the pre-drilled holes at the bottom to drill the holes into the wall that wasnt that hard But for the top anchor/screws, the cabinet did not have pre-drilled holes and I was not about to guess !! So I used alien tape to tape the top wood bar to the unit as shown in pic then took the cabinet lined up the bottom holes while holding the cabinet up then I drilled holes through the unit with a small bit just to get the whole going then took it back down then followed the same holes with a bigger bit and it worked for me. It hung level. It was crazy that the pre-holes were not 16” apart when they could have been. I added extra screws to be able to mount them to a stud I didn’t feel comfortable with it not being mounted to a stud. The screws I had were too long gonna have to get some shorter screws. But it’s up & looks so nice DO NOT USE 11/32 bit. Don’t even use 5/16. I use 1/4 and kinda ran the drill in a circle to widen the whole and it was the perfect tight fit All in all I do love the cabinet. Just feel the mounting process could have been instructed more conveniently
