When replacing a fuel tank on a later-model Air Cooled Volkswagen Beetle, it is recommended to replace all overflow hoses at the same time. This molded rubber hose is cut to 9 inches, the correct length to run from your fuel tank to the “T” piece, ensuring proper fit and performance.

Essential when replacing a fuel tank or lines
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.
