  1. If you truely have sugar in the gas tank you will need to remove and replace the fuel filter.

    As it turns out, sugar doesn’t dissolve in gasoline. Pouring sand into the gas tank would have about the same effect as pouring in sugar. The sand or sugar might clog up the filter, and that could disable the car, but it’s not a sure thing.
