Is it easy to change a fuel car into a gas car? How to transform? How much will it cost?

You mean dual fuel? Many places can be changed. The price is around 4000-7000. Some cars can't be loaded, mainly depending on the position of the engine and whether there is a place to put the fuel tank. The most important thing is whether there is a gas station in your local area. I come from Chongqing. We have basically installed taxis and buses here. The disadvantage is the decline in strength.
