Description
Radium Engineering developed the Fuel Surge Tank Install Kit for Mitsubishi Evo 8/9 around the needs of modified street and competition cars, where component compatibility and clean system layout matter as much as outright capacity.
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 03-07 Mitsubishi Evo 8/9 Fuel Surge Tank Kit (FST NOT Incl)
Fitment & Application
Application: Mitsubishi Evo 8/9
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.
