When just about any oil tanker hears the intro of a ChrisFix video, they know they’re going to learn something. In the last episode of his series on repairing a vandalized Chrysler 200, he shows how to flush the fuel system.
Luckily for Chris, the “sugar in the gas tank” myth has been shattered. With a quick demonstration, it shows that sugar doesn’t actually dissolve in gas and therefore doesn’t kill engines. That said, even though the fuel filter will keep the sugar granules from leveling your engine, some work is still required to get the car up and running properly. In case you are only dealing with sugar, the gas tank should be removed and cleaned, then the fuel filter should be replaced.
With a modern vehicle, Chris says it’s a fairly easy job. On the Chrysler 200 that he looks after, the fuel pump and the tank are very easy to access and work. He says removing them would take 30 minutes or less for someone with a little experience. After cleaning the gas tank, Chris moved to clean the fuel filler pipe.
After using a screwdriver to collect as much sugar as possible, the next job was to rinse the pipe with water. While sugar doesn’t dissolve in gasoline, we probably all know it dissolves in water. After the line was flushed, he ran a little isopropyl alcohol to dissolve any moisture.
While this is the only work required for the sugar in your gas tank, Chris also explained how to flush the rest of the fuel system. All the right knowledge to have if you have other issues like a rusty tank or filling with the wrong fuel.
