HFP-PR50 is a premium OEM replacement fuel pressure regulator engineered for fuel-injected off-road, dual-sport, and supermoto motorcycles. 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.
Features & Benefits:
- Precision 350 kPa Calibration: Factory-set at 50 PSI to ensure the exact fuel delivery mapping required by KTM, Husqvarna, and Husaberg engine control units (ECUs).
- Eliminates EFI Bogging: Corrects common low-end stumbles and sudden stalling issues caused by a bleeding or failing factory pressure bypass valve.
- High-Performance Synthetic Rubber: Internals feature premium, fuel-safe fluorocarbon elastomers and synthetic rubber compounds to resist degradation from modern ethanol-blended fuels (E10).
- Direct Drop-In Fitment: Precision machined to seat perfectly inside the original in-tank fuel pump assembly or hanger module without any modification.
- Advanced Diaphragm Design: Features an industrial-grade, multi-layer diaphragm fabric engineered to retain its structural spring rate under extreme heat and rapid throttle changes.
- Restores Throttle Response: Stabilizes fuel rail pressure to ensure crisp, instantaneous throttle response during aggressive acceleration and deceleration.
- Broad Euro-Platform Support: Specifically tailored for modern high-revving thumpers, from the 250/350 SX-F motocross bikes to the long-range 690 and 701 adventure builds.
