The lpg brain (lpg regulator) used in the vehicles can be used in a red one, but if it is solid, it can be a normal lpg tank as a tube boiler, as in this video, it can be a kitchen tube or a picnic tube, but as you know, the gas in them is a little more expensive, I don’t know how to connect the water to the tube brain, but if the brain is in the exhaust manifold. next to you it will get warmer if you can’t provide heating, your brain will start to freeze, you have to deal with it, you don’t have a brain, don’t forget, you can only run it steadily without the brain, by pressing the gas pedal, you can open the cylinder as much as you want, when you release the gas pedal, the gas coming from the cylinder will be too much, so you need to cut down the tube a little. This method only works with water engine, etc. Test driving of Ferguson Armadillo constrructed at Danmarks Ferguson Museum
