Radium Engineering Diaphragm Service Replacement FPR Universal MPR/FST-R/DMR

Radium Engineering Diaphragm Service Replacement FPR

This is a genuine Radium Engineering replacement diaphragm, built to the same motorsport grade tolerances as the regulators it services. Radium components are trusted by tuners and race teams running serious fuel system builds, and this diaphragm keeps that regulation accurate as your Radium FPR sees hard use over time.

This listing covers the service diaphragm for the Radium MPR (Multi-Pump Regulator), Radium FST-R (Fuel Surge Tank with Regulator), and Radium DMR (Direct Mount Regulator). It's a direct service replacement across all three regulator platforms, so there's no need to replace the entire unit when only the diaphragm has worn out.
