What should occur to the fill pipe when a customer is converting to an alternative fuel?

When a customer is converting to an alternative fuel, the fill pipe should be removed. This is due to safety and compatibility considerations. A fill pipe designed for one type of fuel may not be suitable for alternative fuel types, and unoccupied fill pipes can become a hazard if left in place.

Removing the fill pipe helps prevent any potential accidental filling with the wrong fuel, which can lead to dangerous situations, such as leaks or fires. Additionally, leaving the fill pipe in place could lead to confusion in the future during maintenance or further fuel conversions. Overall, proper removal ensures that the system is safely and effectively prepared for the new fuel type being implemented.
