Description
Radium Engineering developed the 2006+ Lotus Elise/Exige T4E Header Set 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-system electrical hardware has to carry pump current reliably in an environment exposed to heat, vibration and fuel vapor. Correctly sized wiring, sealed pass-throughs and secure terminals are as important to fuel delivery as the pump itself.
Product-Specific Details
Allows for simple wiring harness without permanent damage or modification to the factory harness
Technical Notes
Pump wiring should be sized around real current draw and protected with appropriate relays and fusing. High-flow pumps can exceed the capacity of factory wiring, particularly when multiple pumps are operated simultaneously.
Radium Part Number
RAD17-0011
Enthusiast Notes
For a competition-oriented fuel system, clean wiring is reliability hardware. Use proper strain relief, circuit protection and grounding, and verify voltage at the pump under load.
Before Ordering
Confirm pump count, current draw, connector/terminal style and the vehicle' relay/fuse strategy before ordering.
