Description
The Radium Engineering Fuel Surge Tank for Regulated is intended for performance builds that demand a more deliberate approach than simply adapting the factory hardware. It gives the installer a Radium-specific foundation for the listed application.
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
Updated design for 2023. Fuel surge tank with integrated fuel pressure regulator. Utilizes an internal fuel pump (sold separately). Separate fuel pressure regulator not needed. For EFI systems only. Universal design.
Fitment & Application
Application: Regulated
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.
Radium Part Number
RAD20-1933
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.
