Overview
HFP-386-X2RT5F2 is a premium OEM replacement in-tank electric fuel pump master rebuild kit engineered to fully restore electronic fuel injection (EFI) performance and system pressure to Kawasaki utility vehicles and side-by-sides. Serving as a direct-fit internal component overhaul for factory part numbers 49040-0830 and 49040-0782, this master package refreshes the critical high-wear delivery components nested inside the original in-tank module assembly. It features comprehensive database fitment compatibility for workhorse utility and sport side-by-side models from 2020 through 2026, including the Mule 4000 (Standard, Trans), Mule 4010 (4X4, Trans4x4, Police), Mule SX 4x4 (FI, XC, FE), and the high-performance Teryx KRX 1000 and Teryx KRX4 1000 sport platforms. It systematically resolves common fuel-starvation bugs caused by heavy trail vibrations, clogged filtration elements, and worn motor armatures, such as hard cold starting, mid-range engine bogging, lean deceleration backfiring, rough idling, or a total loss of fuel rail pressure under heavy work loads.
Utility vehicles and sport side-by-sides face extremely demanding duty cycles, navigating fine trail dust, mud splashes, and prolonged periods of seasonal storage. Water condensation and fine silt often slip into the fuel tank, leading to internal rust scale and sticky varnish that clogs the original filter media and overworks the factory electric pump motor.
HFP-386-X2RT5F2 addresses these fuel system failures by renewing all primary in-tank wear components at once. The kit pairs a quiet, cool-running fuel pump core with a factory-calibrated fuel pressure regulator to maintain correct operational pressure. A dual-stage filtration setup, featuring a high-capacity inline fuel filter and a fine-mesh pickup strainer, blocks microscopic tank debris from reaching the engine. The critical baseplate tank seal is molded from a high-performance synthetic rubber compound. This advanced elastomer maintains its shape and compression holding strength without swelling, checking, or weeping when continuously submerged in modern pump gas, performance additives, and ethanol-blended fuels.
Features & Benefits:
- All-In-One Delivery Overhaul: Concurrently replaces the pump core, filter, strainer, 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.
- Dual-Stage Filtration Protection: Combines a high-efficiency suction strainer and a high-capacity inline filter to lock out fine tank silt and varnish before it reaches precision injector pins.
- Preserves Original Hanger Assemblies: Meticulously dimensioned to slide straight into your factory Kawasaki internal plastic hanger basket, ensuring the original fuel level float remains fully functional.
