QFS-303-URT is a professional-grade fuel pump rebuild kit specifically engineered for Arctic Cat (Textron) and Kymco ATVs and UTVs.
This comprehensive kit targets the high-performance Wildcat XX and the versatile Alterra series (500, 550, 570, and 700). In off-road environments, fuel systems are subjected to extreme vibration, heat, and potential debris contamination.
A failing pump or a clogged internal regulator often results in engine bogging, hard hot-restarts, or a “lean” condition that can cause permanent engine damage.
This “URT” kit provides everything needed to fully refresh the factory fuel module, including a precision-calibrated fuel pressure regulator and a fresh tank seal. By replacing these components together, you restore factory-spec rail pressure and ensure a leak-free seal, providing a reliable and cost-effective alternative to purchasing an expensive complete OEM assembly.
Features & Benefits:
- Complete Module Refresh: Includes the high-pressure fuel pump, gradient-density strainer, calibrated pressure regulator, rubber grommet, and high-performance synthetic rubber tank seal.
- Wildcat XX & Alterra Optimized: Specifically calibrated to meet the fueling demands of Arctic Cat’s modern EFI platforms, ensuring smooth power delivery across all RPMs.
- Stable High-Pressure Output: Maintains the exact rail pressure required for optimal fuel atomization, preventing the “stuttering” often felt during aggressive trail riding.
- Enhanced Durability: Constructed with upgraded internal polymers and carbon commutators to withstand the rigors of off-road use and long periods of seasonal storage.
- Vibration Resistant: Engineered with a robust turbine design to minimize internal wear caused by the high-frequency vibrations common in ATVs and Side-by-Sides.
- Ethanol Compatibility: Fully compatible with E10 and modern ethanol-blended pump gasolines, protecting internal diaphragms and seals from premature degradation.
- Direct-Fit Core: Designed as a drop-in replacement for the original pump and regulator within the factory canister, simplifying the repair process.
