QFS OEM Replacement Fuel Pump Module Assembly for 2015-2019 Beta 350 RR #8000H3424

The QFS HFP-A489-R2 is a complete direct-fit OEM replacement fuel pump module assembly engineered to restore consistent, high-pressure fuel delivery on 2015–2019 Beta 4-stroke enduro machines (350 RR, 390 RR, 430 RR, 480 RR, 500 RR-S) and 2011–2014 Husqvarna TE/TXC 250 and 310 off-road motorcycles. Directly replacing factory OEM part numbers 8000H3424, 031.40.048.82.00, and 031.40.024.00.00, this pre-assembled module drops directly into the stock fuel cell to solve severe off-road performance issues, including high-RPM flame-outs, lean popping under sudden throttle snaps, hard starting when hot, extended cranking times, and sudden power drop-offs during aggressive trail riding or technical hard-enduro climbs.

Modern high-performance four-stroke dirt bike engines place intense physical, thermal, and chemical demands on in-tank fuel system components. Extended seasonal storage, humidity condensation, and standing pump fuel containing ethanol lead to phase separation, rust formation, and thick varnish buildup inside the module. Severe off-season fuel degradation clogs fine intake strainers, seizes internal motor armatures, and degrades factory pressure regulator springs. Furthermore, severe engine heat-soak and constant frame vibration cause stock rubber seals and internal line connections to swell, crack, or split, creating internal pressure bypass leaks that rob the engine of required working rail pressure under load.

Engineered as a complete drop-in restoration module, the HFP-A489-R2 replaces the entire internal tank setup—including the electric pump motor, calibrated pressure regulator, primary intake strainer, and main tank seal. The internal electric motor utilizes a precision-balanced turbine impeller to deliver smooth, pulsation-free fuel flow while reducing internal friction and operational heat. To withstand aggressive modern pump fuels, race gas blends, and harsh environmental conditions, all included tank flange gaskets, internal grommets, and O-rings are molded from high-performance synthetic rubber (industrial-grade FKM). This advanced elastomeric material resists chemical breakdown, swelling, and hardening across extreme operating temperature ranges, ensuring a leak-free pressure seal and protecting fuel injectors against engine-damaging lean conditions.
