What steps should one take to clean and restore the fuel system after someone has put sugar in your gas tank?

Replace the fuel injectors or clean them and replace your fuel filter. You may have to replace your fuel filter a few times. If you can, take your gas tank out and wash it with water. Sugar will not turn to sluge or 'cement' in your gas tank, actually sugar doesn't even dissolve in gasoline. It will however block your fuel injectors and fuel filter. # idid that wash gastank and put a filter and injector it ran for a minute and got hot and now it wont crank at all it has lockup so what do i do to make it run
