Description
Radium Fuel Hanger Surge Tank Install Kit - BMW E46 3-Series / M3 (Excluding Convertible)
Suits:
- BMW 3-Series E46 — Sedan, Coupe, Touring (excluding Convertible)
- BMW M3 E46
The Radium Engineering Fuel Hanger Surge Tank Install Kit is a comprehensive installation package for fitting a Radium FHST (Fuel Hanger Surge Tank) to the BMW E46 3-Series and M3. The FHST is sold separately. This kit includes all necessary hardware, brackets, fittings, hose, and wiring components to complete the installation without cutting, drilling, or permanent modifications to the vehicle.
The OEM fuel pump is repurposed to keep the surge tank full, with excess fuel returning to the OEM fuel tank. The FHST pump then feeds the engine directly, ensuring continuous fuel supply even if the OEM pump becomes momentarily starved — ideal for high-power and track builds where fuel starvation is a concern.
Kit Includes
- E46-specific stainless steel or anodised aluminium FHST mounting bracket
- AN adapter fittings and hose ends
- Fuel hose for custom routing
- Wiring components with relay, fuse, and connectors
- Stainless steel mounting hardware
Required (sold separately)
- Radium FHST (Fuel Hanger Surge Tank) — see compatible FHST options
