How does a 1987 F150 switch between fuel tanks?

The 1987 Ford F-150 uses a fuel tank switching system that is typically controlled by a switch located on the dashboard. This switch allows the driver to select either the front or rear fuel tank. The vehicle is equipped with a fuel selector valve that directs fuel from the chosen tank to the engine. When the switch is activated, the valve changes position, allowing the engine to draw fuel from the selected tank while preventing fuel flow from the other tank.
