Where is the fuel shut-off switch for a 1989 Ford Econoline 460 Engine?

There isn't a readily accessible fuel shut-off switch on a 1989 Ford Econoline with a 460 engine like there might be on some other vehicles. Ford didn't typically include them as standard equipment on these trucks. To stop fuel flow, you would need to disconnect the fuel pump's electrical connection or, in an emergency, potentially the fuel line itself (though this is messy and potentially dangerous). Always remember to follow proper safety procedures if working with fuel lines.
