Radium Engineering Diaphragm Service Replacement FPD

For a properly planned performance build, the Radium Engineering Diaphragm Service Replacement FPD reduces pressure pulsations created by injector opening and fuel-pump operation so pressure at the rail stays more stable. Smoother fuel pressure can improve consistency in high-flow EFI systems, particularly when injector events or rigid plumbing create noticeable pressure oscillation.

Choose the correct pressure range and mounting thread. Radium specifies these dampers are not for the low-pressure side of mechanical direct-injection pumps.
