This precision-calibrated component serves as a direct drop-in replacement for factory part numbers 75007088012 and 27007088112, supporting an extensive lineup of high-performance European single-cylinder machines including the KTM 690 series, Husqvarna 701 platforms, and fuel-injected Husaberg FE models. Electronic fuel injection systems on hard-ridden dirt and street bikes demand unyielding pressure consistency; a fatigued factory regulator diaphragm will bleed off pressure, causing off-throttle flame-outs, severe engine bogging, lean-out hesitation, or rough idling. HFP-PR50 completely restores your bike’s fueling geometry by maintaining a strict, factory-specified operating threshold of 350 kPa (50 PSI) across the entire RPM spread. Built to survive the harsh heat-soak cycles of tight single-track trails and the high-vibration stress of professional motocross tracks, the internal bypass valve is fitted with high-performance synthetic rubber seals to guarantee zero fuel bypass and complete resistance to fuel-borne contaminants.\u003c\/p\u003e\n\u003cdiv style=\"margin-top: 30px;\"\u003e\n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/u\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision 350 kPa Calibration: \u003c\/strong\u003eFactory-set at 50 PSI to ensure the exact fuel delivery mapping required by KTM, Husqvarna, and Husaberg engine control units (ECUs).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminates EFI Bogging: \u003c\/strong\u003eCorrects common low-end stumbles and sudden stalling issues caused by a bleeding or failing factory pressure bypass valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Performance Synthetic Rubber: \u003c\/strong\u003eInternals feature premium, fuel-safe fluorocarbon elastomers and synthetic rubber compounds to resist degradation from modern ethanol-blended fuels (E10).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Drop-In Fitment: \u003c\/strong\u003ePrecision machined to seat perfectly inside the original in-tank fuel pump assembly or hanger module without any modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Diaphragm Design: \u003c\/strong\u003eFeatures an industrial-grade, multi-layer diaphragm fabric engineered to retain its structural spring rate under extreme heat and rapid throttle changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestores Throttle Response: \u003c\/strong\u003eStabilizes fuel rail pressure to ensure crisp, instantaneous throttle response during aggressive acceleration and deceleration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad Euro-Platform Support: \u003c\/strong\u003eSpecifically tailored for modern high-revving thumpers, from the 250\/350 SX-F motocross bikes to the long-range 690 and 701 adventure builds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-top: 30px;\"\u003e\u003cp\u003e\u003cstrong\u003eTHE IDEAL REPLACEMENT FOR OEM #:\u003c\/strong\u003e 75007088012, 27007088112\u003c\/p\u003e\u003c\/div\u003e\n\u003cdiv style=\"margin-top: 30px;\"\u003e\u003cp\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e 350 kPa Fuel Pressure Regulator\u003c\/p\u003e\u003c\/div\u003e\n\u003cdiv style=\"margin-top: 30px;\"\u003e\u003cp\u003e\u003cstrong\u003eWARNING: \u003c\/strong\u003eThis product can expose you to chemicals which are known to the State of California to cause cancer and birth defects or other reproductive harm.
