Description
The Radium Engineering Fuel Surge Tank for BMW E9x 3-Series (N54/N55) Regulated is engineered as a purpose-built solution for enthusiasts who want the surrounding system to be easier to package, service and trust under hard use.
Why This Upgrade Matters
Fuel surge tanks add a reserve of fuel between the main tank and engine so the pressure-side pump can remain supplied when fuel moves away from the factory pickup under braking, cornering or acceleration. They are especially relevant to track, time-attack, autocross and high-power applications where momentary fuel starvation is unacceptable.
Product-Specific Details
Radium Engineering Surge Tanks are During hard acceleration, braking, cornering, or low fuel conditions, fuel can slosh away from the factory fuel pump pickup, causing dangerous lean conditions. A surge tank acts as a secondary fuel reservoir, ensuring a constant supply of fuel to your engine when it needs it most. Manufactured from high-quality aluminum and engineered for maximum reliability, Radium surge tanks are a popular solution for turbocharged, supercharged, track-driven, drag racing, drifting, and off-road vehicles. Understanding Radium Surge Tank Options Radium offers several surge tank configurations to suit different horsepower goals and fuel system requirements: Single Pump Surge Tanks Ideal for moderate-performance vehicles that need protection against fuel starvation without requiring extreme fuel flow. A single-pump setup is commonly used for street cars, mild.

Fitment style: Application-Specific
Technical Notes
A conventional surge tank still requires a correctly sized lift-pump circuit, pressure-side pump, feed/return plumbing and electrical supply. The lift pump' job is to keep the reservoir replenished; the surge-tank pump is what feeds the engine.

Enthusiast Notes
On a track car, a surge tank is insurance against the moment when the main tank pickup uncovers in a long corner or heavy braking zone. Size the pumps for the engine' actual fuel demand and leave electrical and thermal headroom.
Before Ordering
Confirm compatible pump model, pump quantity, fuel type, mounting location, line sizes and electrical requirements. Many surge-tank assemblies require pumps, wiring, filters, regulators or mounting hardware to be selected separately.
