    What happens when syrup is put in a gas tank?

    A:

    The effects of putting syrup in the gas tank of a car depend on how far the syrup gets into the fuel system. If the car is started and run for any length of time, the syrup can end up clogging the fuel filter, which can cause the flow of fuel to be restricted, and in turn can cause the engine to stop running. If the syrup gets to the filter, the gas tank may need to be replaced.
