Where is fuel shutoff switch on 99 Mercury Mountaineer?

The 1999 Mercury Mountaineer does not have a readily accessible fuel shutoff switch like some other vehicles. There's no easily located switch you can flip to immediately stop fuel flow in an emergency. The fuel system relies on electrical components and the fuel pump to function. In case of a fire or other emergency, your best course of action is to disconnect the negative battery cable. This will cut power to the fuel pump, preventing further fuel flow.
