Description
The Radium Engineering Multi-Port Regulator (MPR) for Green 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 pressure control is fundamental to injector consistency and repeatable tuning. A regulator must manage return flow while maintaining the pressure strategy required by the injectors and ECU, particularly as pump flow and engine demand increase.
Product-Specific Details
Universal adjustable fuel pressure regulator for EFI vehicles. Ideal for pump flows from 200 lph to 1400 lph. E85 compatible. Green anodized top. Tool-free pressure adjustment.
Fitment & Application
Application: Green
Fitment style: Application-Specific
Technical Notes
Base pressure should be set with the system configured as required by the engine management strategy. Pump flow affects the regulator' operating range, and boosted applications may require a manifold-reference connection where the specific regulator supports it.
Radium Part Number
RAD20-1100-01
Enthusiast Notes
For tuned cars, stable pressure is part of stable fueling. Set the regulator with a gauge or sensor and validate pressure behavior under load rather than assuming the static setting tells the whole story.
Before Ordering
Confirm required base-pressure range, total pump flow, feed/return port sizes and whether vacuum/boost reference is required. A regulator should be sized as part of the complete fuel system.
