Because Details Matter

An overflow hose may seem minor, but it plays a vital role in keeping fuel where it belongs. A fresh rubber line restores that crisp, confident connection from the tank to the “T” piece — exactly as Volkswagen engineered it. Replacing this hose is more than maintenance; it’s preserving the authentic feel of your classic Beetle’s fuel system, and that’s the detail that keeps it true.
