Every time an injector opens and closes, it sends a pressure pulse rippling back through the fuel rail. Left unchecked, those pulses cause unstable fuel pressure, idle surge with high-flow injectors, and lean AFR spikes that are notoriously difficult to tune around. The FPD-R absorbs these oscillations via an internal diaphragm, keeping rail pressure stable across the entire RPM range.\u003c\/p\u003e\n\n\u003cp\u003eThis listing covers the \u003cstrong\u003eFPD-R\u003c\/strong\u003e model with a \u003cstrong\u003e3\/8\" NPT\u003c\/strong\u003e male threaded fitting — SKU \u003cstrong\u003e20-0178\u003c\/strong\u003e. This is a universal fitment dampener suited to any vehicle where the base static fuel pressure falls within the 40–70 PSI operating range. For systems running higher base static pressures (up to 105 PSI), the \u003cstrong\u003eFPD-XR\u003c\/strong\u003e is the appropriate choice.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The FPD-R is rated for a base static fuel pressure of 40–70 PSI. On boosted vehicles running a rising-rate fuel pressure regulator, dynamic pressure above 70 PSI is acceptable — however the vacuum\/boost reference line must be connected to maintain correct diaphragm operation. Base static pressure must still fall within the specified range.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCNC-machined anodised aluminium body and laser-engraved top — green anodised cap identifies the R-series range\u003c\/li\u003e\n  \u003cli\u003e3\/8\" NPT male threaded fitting with tapered thread seal\u003c\/li\u003e\n  \u003cli\u003eVacuum\/boost reference port included — essential for boosted rising-rate FPR applications\u003c\/li\u003e\n  \u003cli\u003eMounts at any angle including inverted — direct fuel rail mounting recommended for best results\u003c\/li\u003e\n  \u003cli\u003eCompatible with all fuel types: pump petrol, E85, ethanol, methanol, and flex fuel\u003c\/li\u003e\n  \u003cli\u003eStainless steel hardware throughout\u003c\/li\u003e\n  \u003cli\u003eIncludes 4mm ID rubber vacuum hose and vacuum hose Y-fitting\u003c\/li\u003e\n  \u003cli\u003eBase static pressure range: 40–70 PSI\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA to motorsport-grade tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eCompatibility details and fitment notes are provided in the tabs above.
