How does a ford E350 dual fuel tanks operate?

The Ford E350 with dual fuel tanks operates by having two separate fuel tanks that supply fuel to the engine. The vehicle typically features a switch that allows the driver to choose which tank to draw fuel from, often indicated by a gauge on the dashboard. When one tank reaches a low fuel level, the driver can switch to the other tank to continue driving without interruption. This setup is particularly useful for extending the vehicle's range between refueling stops.
