how do i convert a natural gas vehicle back to regular gas?
Most of the time, when a vehicle is changed from gasoline to propane or natural gas, it’s configured as dual fuel and there is a way to switch from natural gas/propane to gasoline. If that is what yours is, just leave it switched to gasoline and drive it. If not, no one has any idea. You will have to find whoever converted it over and ask, or take it to your mechanic and ask.

If it was originally manufactured as a natural gas vehicle, it would probably be easier to replace the vehicle.
You will need a fuel tank, pump, lines, fuel filter, and a complete fuel rail with pressure regulator and injectors. You will have to install an evaporative control system. You will also need new software to control it all.
If it is a dual fuel vehicle then the previous advice of just use the gasoline system will work fine.
