Radium Fuel Surge Tank Kit for 2001-08 BMW M3 & 3-Series [E46]

This comprehensive installation kit includes everything needed to install a Radium Engineering Single Walbro, AEM, Aeromotive, or Deatchwerks equipped fuel surge tank (FST) in a 1999-2006 BMW E46 3-series or M3, with the exception of convertibles. Much like an electrical capacitor can even out hard electrical system loads by temporarily storing energy, the surge tank holds a charge of fuel.

A Fuel Surge tank prevents fuel starvation from occurring under hard cornering and braking as the fuel in your tank sloshes to one side or the other, during which the fuel can slosh away from the fuel pump pickup, suddenly depriving your engine of fuel! By adding a second small tank that's charged with gas in line between the fuel pump and engine, though the fuel has sloshed away from the pickup, the surge tank keeps your car happily fed by ensuring the fuel keeps flowing to the pump.

All Radium FSTs feature anodized aluminum surfaces, submersible hose, etc. to make them alcohol (ethanol/methanol/E85) compliant.

This BMW E46-Specific install kit mounts the Surge Tank in a collision-safe area of the trunk behind the rear seat. The bolt-on powdercoated aluminum mounting bracket features rubber isolating grommets to reduce fuel pump noise.

Also included is a fully assembled plug and play wiring harness featuring a weatherproof fuse and relay to drive the FST's fuel pump. A Delphi weatherpak connector is also provided for the fuel pump trigger activation to make the entire system modular.

 

 

Features:

  • Prevents Fuel Starvation That Normally Occurs Under Hard Braking & Cornering
  • Small Tank Pre-Charged With Fuel acts like a Capacitor and ensures fuel keeps flowing to the motor during performance driving maneuvers
  • Kit Mounts Surge Tank In A Collision-Safe Area
  • Alcohol/Methanol/Ethanol/E85/E30-Fuel Compliant!

 

 

All Radium FSTs feature anodized aluminum surfaces, submersible hose, etc. to make them alcohol (ethanol/methanol/E85) compliant.

 



The BMW install kit locates the FST in a collision-safe area of the trunk behind the rear seat. The bolt-on powdercoated aluminum mounting bracket features rubber isolating grommets to reduce fuel pump noise.

Also included is a fully assembled plug and play wiring harness featuring a weatherproof fuse and relay to drive the FST's fuel pump. A Delphi weatherpak connector is also provided for the fuel pump trigger activation to make the entire system modular.

Included are 8 PTFE hoses which are cut to length and preassembled. The PTFE hose is great 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. These PTFE hoses use anodized aluminum hose ends 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 PTFE hoses mate at a junction point in the trunk using 4 bulkheads fittings and a billet aluminum plate for interior aesthetics.
