Radium Engineering Fuel Surge Tank Install Kit (Excl. Convertible) - BMW 3-Series (E46)
This Radium Engineering installation kit (SKU 20-0974) provides everything needed to mount a Radium fuel surge tank in the boot of the BMW E46 3-Series and M3. The tank sits in a collision-safe area behind the rear seat on a bolt-on aluminium bracket, with rubber isolating grommets to cut fuel pump noise.

How does a RADIUM Fuel Surge Tank work?
Wiring is modular, with a weatherproof fuse and relay to run the surge tank pump and a Delphi Weatherpak connector for the pump trigger. Pre-assembled PTFE hoses, cut to length, meet at a bulkhead plate with four bulkhead fittings for a tidy interior pass-through. Suits sedan, coupe and Touring body styles; convertibles are not supported.
Note: This is the installation kit only. The fuel surge tank and the surge tank fuel pump are sold separately. Not compatible with E46 convertibles. Installation by a professional is recommended.
