Someone put sugar in my gas tank.
Hello. The fuel tank must be drained, removed from the vehicle, rinsed out, and dried to try to remove as much sugar as possible from the tank. The fuel pump and fuel filter should be replaced, and the line between the fuel filter and tank should be washed, and blown out. You should install a locking gas cap to avoid any further contamination of the fuel tank. The fuel with sugar would be considered hazardous waste, therefore you should find a shop that has the means of disposing of the contaminated fuel, as well as the fuel pump replacement, and other services mentioned above. There might be a fee to go along with the contaminated fuel disposal.
