Overview
HFP-389-U3RTF3 is a premium OEM replacement in-tank fuel pump master rebuild kit engineered to fully restore electronic fuel injection (EFI) performance and line pressure to KTM, Husaberg, and Husqvarna motorcycles. Serving as a direct internal component overhaul for factory part numbers 75007088011, 75007088111, 75007088211, 75007088311, 75007088511, 75007089000, and 81207088011, this master package refreshes the primary pressurized delivery components nested inside the original in-tank module assembly. It features comprehensive cataloging compatibility across single-cylinder enduros, supermotos, and motocross models from 2007 through 2018, including the KTM 690 Duke, 690 Enduro/R, 690 SMC/R, 250 SX-F, and 350 SX-F, the Husaberg FE 390/450/570, FS 570, and FX 450, as well as the Husqvarna 701 Enduro and 701 Supermoto. It systematically corrects critical fueling bugs caused by worn motors, leaking bypass valves, or clogged filters, such as hard hot starting, mid-range engine bogging, flame-outs under sudden throttle input, rough idling, and high-RPM fuel pressure drops.
Off-road and dual-sport motorcycles endure extreme vibration, heat-soak, and frequent off-season storage layups. Over time, fuel phase separation and fine dirt intrusion create internal varnish and rust scale that clog the intake strainers and overwork the stock pump motor. Operating a high-compression single-cylinder engine with a failing fuel pump causes lean air-fuel ratios that lead to overheating, poor throttle response, and engine stalling.
HFP-389-U3RTF3 addresses these fueling failures by renewing all major internal delivery wear items simultaneously. The kit pairs a quiet, cool-running fuel pump core with a factory-calibrated fuel pressure regulator to maintain correct fuel rail operating pressure. A high-efficiency inline fuel filter and specialized fuel strainers work together to block microscopic debris before it reaches the precision fuel injector. The structural baseplate tank seal is molded from a high-performance synthetic rubber compound, maintaining its shape and compression strength without swelling, checking, or weeping when continuously submerged in modern pump gas, race additives, and ethanol-blended fuels.
Features & Benefits:
- All-In-One Delivery Overhaul: Concurrently replaces the pump core, internal filter, intake strainers, regulator, and base seal to eliminate intermittent stalling bugs and rail pressure drop-offs.
- Calibrated Line Pressure Control: Restores factory-exact fuel rail operating pressure to clear high-speed lean conditions, flat spots, and mid-range throttle hesitation.
- High-Performance Synthetic Rubber: The supplied structural tank gasket and internal pathway seals are molded from premium industrial-grade FKM to resist modern ethanol fuel breakdown.
- Advanced Turbine Design Core: Built with a balanced internal turbine mechanism that draws low electrical current while minimizing heat-soak inside the fuel tank cavity.
- Multi-Stage Filtration Protection: Combines high-efficiency suction strainers and an inline filter to lock out fine tank silt and varnish before it reaches precision injector nozzles.
- Preserves Original Hanger Assemblies: Meticulously dimensioned to slide straight into your factory plastic internal hanger basket, ensuring the original fuel level float and mounting system remain fully functional.
