Go Natural CNG develops EPA and ARB certified natural gas engines and hydraulic compressors for fuel stations. We sell conversion kits, fuel interface modules and CNG hoses. In our partnership with Edge Products, we provide the first 4-inch touch screen in cab display for natural gas conversions providing vehicle owners and drivers with detailed information about their natural gas vehicle. We provide dedicated and bi-fuel conversions that allow a vehicle to run on either gasoline or natural gas.
