The \u003cstrong\u003eRadium Engineering V2 FPD-XR\u003c\/strong\u003e absorbs those oscillations and stabilises fuel rail pressure across the full RPM range. Designed and manufactured in the USA, Radium FPDs are trusted by professional motorsport teams and serious enthusiasts worldwide — and are exclusively distributed in Australia by Coore.\u003c\/p\u003e\n\n\u003cp\u003eThis listing covers the \u003cstrong\u003e20-0777 V2 FPD-XR\u003c\/strong\u003e with \u003cstrong\u003e8AN ORB\u003c\/strong\u003e male threads. This is the extended range damper (black anodised top) suited to high-pressure fuel systems with a base static pressure of 40–105 psi. If your base static pressure falls within 40–70 psi, the shorter \u003cstrong\u003eFPD-R (20-0776)\u003c\/strong\u003e may be more appropriate for space-constrained installations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The 40–105 psi range refers to base static fuel pressure only — measured with the pump running and no vacuum line connected to the regulator. Dynamic pressure rises produced by a rising rate fuel pressure regulator under boost are acceptable beyond this range, provided base static pressure is set within the specified window and the vacuum\/boost reference line is connected.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eExtended base static pressure range: 40–105 psi — suits a wide variety of high-pressure and boosted fuel systems\u003c\/li\u003e\n  \u003cli\u003eVacuum\/boost reference port — keeps damper performance correct under boost when used with a rising rate FPR\u003c\/li\u003e\n  \u003cli\u003eV2 design: 360° swivel vacuum port can be clocked after installation for easy hose routing in any orientation\u003c\/li\u003e\n  \u003cli\u003e8AN ORB male threads with Viton O-ring seal — compatible with standard AN fuel rail fittings\u003c\/li\u003e\n  \u003cli\u003eMounts at any angle including upside down — no restriction on fuel rail orientation\u003c\/li\u003e\n  \u003cli\u003eE85, alcohol, and all common fuel types compatible\u003c\/li\u003e\n  \u003cli\u003eAnodised and laser engraved aluminium housing — permanent identification, premium finish\u003c\/li\u003e\n  \u003cli\u003eStainless steel hardware throughout\u003c\/li\u003e\n  \u003cli\u003eKit includes: anodised aluminium body and black top, stainless hardware, 4mm ID rubber vacuum hose, and vacuum hose Y-fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFull installation instructions are available for download from Radium Engineering.
