Fuel Tool MC300 Check Valve Rebuild Kit – Fits Harley‑Davidson 2001‑2025 – Replaces Leaking Fuel Check Valves

The Fuel Tool MC300 Check Valve Rebuild Kit allows you to repair a leaking Harley‑Davidson fuel check valve without replacing the entire fuel line assembly. This kit includes premium components engineered to restore proper sealing, fuel pressure retention, and long‑term reliability.
Instead of purchasing an expensive OEM check valve and fuel line, the MC300 gives you a fast, cost‑effective solution using high‑quality Dupont Viton® O‑rings, a nickel‑plated brass valve, and a stainless‑steel spring. When paired with the Fuel Tool MC400 installation tool (sold separately), the rebuild can be performed without removing the fuel tank.
Proudly Made in the USA, this is the industry’s first and only dedicated Harley check‑valve rebuild kit.
