Fuel Tool Harley Check Valve Tool + Rebuild Kit Combo – MC400 & MC300 – Fits 2001‑2025 Harley‑Davidson (Except V‑Rod)

This Fuel Tool MC400 + MC300 Combo Kit gives Harley‑Davidson owners everything needed to service and rebuild the fuel check valve without removing the fuel tank. Instead of replacing the entire check valve and fuel line assembly, this kit allows you to quickly rebuild the valve using high‑quality components and the industry’s only dedicated installation tool.
The MC400 Check Valve Tool enables fast, professional removal and installation of check‑valve O‑rings and rebuild components directly on the motorcycle. The MC300 Rebuild Kit includes premium Dupont Viton® O‑rings, a solid nickel‑plated brass valve, and a stainless‑steel spring — all engineered for long‑term durability and leak‑free performance.
This combo saves significant time and money, especially on late‑model Harley‑Davidsons where the OEM check valve and fuel line assemblies are expensive and often backordered. Proudly Made in the USA, this is the industry’s first and only complete check‑valve rebuild solution.
