This comprehensive installation kit includes everything needed to install a Radium fuel surge tank. The base price is for the installation kit ONLY. The fuel surge tank (FST) is sold separately. It can be purchased HERE.

Here is an informative video on how a Radium Fuel Surge Tank works:

The BMW install kit locates the FST in a collision-safe area of the trunk behind the rear seat. The bolt-on aluminum mounting bracket features rubber isolating grommets to reduce fuel pump noise. Also included is a weatherproof fuse and relay to drive the new FST fuel pump. A Delphi weatherpak connector is also provided for the fuel pump trigger activation to make the entire system modular.

As shown above, four 6AN PTFE hoses are provided which are cut to length and preassembled. 

The PTFE hoses mate at a junction point in the trunk using the bulkead plate and 4 bulkheads fittings (shown above) for interior aesthetics.
