It will not damage the engine but may damage the fuel pump
Someone probably put sugar in your gas tank.
Just leave it. It will not harm your engine. Make sure your tank is full and drive. The gas will dilute and break down the syrup. Sugar and various other contaminants do no harm to engines, despite common beliefs.

Fall to the bottom of the tank and sit there. Sugar will not dissolve in gasoline. It may clog the fuel filter but it will do not damage to the engine. It is a myth that it will damage an engine.
Empty your tank out, drain the fuel lines, as the gasoline will damage your diesel engine.
