Where is the fuel system cutoff switch on a 96 dodge ram 1500?

The 1996 Dodge Ram 1500 doesn't have a readily accessible fuel system cutoff switch like some vehicles have as standard equipment. There's no single, easily located switch to instantly cut off fuel flow. To stop the fuel flow, you'd need to either disconnect the fuel pump relay or disconnect the fuel pump's power supply at the pump itself (which requires going under the truck). These are not simple procedures and should only be attempted by someone familiar with automotive systems.
