OVERVIEW

The Fuel Tool MC400 and MC300 Combo Kit enables Harley-Davidson owners to service fuel check valves without removing the fuel tank. This combination pairs a dedicated installation tool with a high-quality rebuild kit, allowing rapid component replacement that avoids expensive OEM assembly backorders. Constructed with professional-grade standards and made in the USA, the system restores reliable fuel delivery for compatible models.

ENGINEERING & PERFORMANCE

WHY HARLEY RIDERS CHOOSE THIS

Riders select this combo because it bypasses the delays and costs of sourcing whole new check-valve assemblies while keeping the bike on the stand. The Viton and brass materials guarantee long-term corrosion resistance and seal integrity, reducing the chance of repeat repairs. Direct access without tank drops saves significant labor, making regular maintenance feasible for home mechanics. This targeted rebuild kit aligns perfectly with the fuel system needs of Harley-Davidson models produced between 2001 and 2025.
