Radium Engineering Fuel Hanger Surge Tank Install Kit for BMW E46 3-Series/M3 (Excl. Convertible)

Radium Fuel Hanger Surge Tank Install Kit - BMW E46 3-Series/M3 (Excl. Convertible)

Application: BMW E46 3-Series and M3 (1999-2006) – excludes Convertible
Part Type: Fuel surge tank install kit (FST and pump not included)
Part Number: 20-0974

The Radium Fuel Surge Tank Install Kit mounts a Radium FST in the BMW E46 to eliminate fuel starvation in all driving conditions. The surge tank sits in a collision-safe area of the boot behind the rear seat, on a bolt-on aluminium bracket with rubber isolators to reduce fuel pump noise.

Preassembled 3/8" PTFE hoses, cut to length, meet at an anodised aluminium bulkhead plate in the boot. A weatherproof 40A relay and 25A fuse power the new surge tank pump, and a Delphi Weatherpak connector allows modular pump activation.
