Connecting the Fuel Pump

What happens here

The presenter retrieves an electrical cord, fitted with alligator clips, from the pickup truck's toolbox. He then connects the clips to the truck's battery terminals: the red clip to the positive terminal and the black clip to the negative terminal. Next, he pulls out the fuel hose and nozzle from the portable fuel tank setup and activates the pump's switch, located on the fuel tank, to begin building pressure in the system.

Goal: Establish electrical power to the portable fuel pump
