What causes a fuel tank to overflow in a 1992 Ford F150?
What causes a fuel tank to overflow in a 1992 Ford F150? I can't say how it would have happened, but it seems that when the front tank pump is selected, the rear tank LEVEL SENDER is connected to the gauge, & vice versa. There's a known issue of fuel returning to the wrong tank causing it to overflow, but that's totally different from your symptom. Where is the fuel pump on a 1992 Ford F150? The front pump runs for a short burst when the key is turned on and the selector switch is set for the front tank....
