Dual tanks
What makes the fuel switch tanks when you it the switch? Is it just vacuum from the other fuel pump that makes the valve switch or is it something else? only my front tank works. when you flip it to the rear the gauge will move but it wont run on the rear tank. Is the rear pump just bad?? Truck is a 89 f250, 5.8

About 5 PSI of fuel pressure from the pump in the selected tank. The pressure snaps the mechanical valve/reservoir to the tank that is supplying the fuel pressure.
