The parts added to your vehicle with LPG Conversion need to be assembled. One of the added parts is the filler neck. Generally, it is placed around the bumper due to its ease of assembly. However, this is not your only option. During filling, your vehicle will look like it has original LPG. When used with Simir Depot, it will not be possible to detect whether your vehicle is LPG powered, either from the inside or from the outside.
