The internal diaphragm of the Radium FPD absorbs these oscillating pulses and stabilises fuel pressure, which can help resolve idle surge (especially with high-flow injectors) and erratic lean spikes that are difficult to tune out.\u003c\/p\u003e\u003cp\u003eRadium FPDs use a vacuum\/boost reference port, allowing proper damper performance at elevated fuel pressures – important for boosted engines with a rising-rate fuel pressure regulator. The FPD-R (standard range) suits vehicles with a base fuel pressure between 40 and 70psi. This 20-0178 version has 3\/8\" NPT male threads for direct mounting, the vacuum port can be clocked during tightening, and the damper can be mounted at any angle, including upside down.\u003c\/p\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Stabilisation:\u003c\/strong\u003e Internal diaphragm absorbs injector pulses and stabilises rail pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum\/Boost Reference:\u003c\/strong\u003e Reference port maintains damper performance at elevated fuel pressures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Range:\u003c\/strong\u003e For base static fuel pressures of 40-70psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Mount:\u003c\/strong\u003e 3\/8\" NPT male thread with a clockable vacuum port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Anywhere:\u003c\/strong\u003e Can be mounted at any angle, including upside down\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Compatibility:\u003c\/strong\u003e Safe for all fuel types including E85\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAnodised, laser-engraved aluminium top\u003c\/li\u003e\n\u003cli\u003eAnodised aluminium body with 3\/8\" NPT male threads\u003c\/li\u003e\n\u003cli\u003eStainless steel hardware\u003c\/li\u003e\n\u003cli\u003e4mm ID rubber vacuum hose\u003c\/li\u003e\n\u003cli\u003eVacuum hose Y-fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eOptional Parts\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\n\u003ca href=\"\/products\/radium-fpd-xr-extended-range-fuel-pulse-dampener-3-8-npt\"\u003eRadium Fuel Pulse Damper - Direct Mount (FPD-R \/ FPD-XR) | 8AN ORB or 3\/8\" NPT (20-0179)\u003c\/a\u003e – FPD-XR extended-range version for base fuel pressures of 40-105psi\u003c\/li\u003e\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBase fuel pressure (pump running, no vacuum line connected to the regulator) must be within 40-70psi – for higher base pressures choose the FPD-XR (20-0179)\u003c\/li\u003e\n\u003cli\u003eIf dynamic fuel pressure from a rising-rate regulator goes outside 40-70psi, the vacuum\/boost reference line must be connected\u003c\/li\u003e\n\u003cli\u003eNot suitable for mechanical fuel pumps or high-pressure direct injection pumps – the pulses will quickly rupture the diaphragm\u003c\/li\u003e\n\u003cli\u003eRequires a 3\/8\" NPT female mating port; tapered threads require thread sealant\u003c\/li\u003e\n\u003cli\u003eInstallation instructions are available in the Instructions tab\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003eUniversal – see Application\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eIf you're unsure whether this will fit your vehicle, contact our team of experts via email at \u003ca href=\"mailto:hello@iilumolab.com\"\u003ehello@iilumolab.com\u003c\/a\u003e and send through a few photos of the car for us to verify fitment.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003eWe always recommend professional fitment for guaranteed satisfaction.
