Retro-Fitment of LPG kits

LPG conversion has to be done from a retro fitment centre which is accredited by the RTO only. They not only convert your vehicles to a duel fuel system but also help you in getting the necessary permission to ply your vehicle on the roads.LPG Conversion Kits

BIS and ARAI Standards

LPG kits have to be compliant with the stringent rules that are set by the Bureau of Indian Standards. The retro fit LPG kits must also come with the approval of ARAI.


The LPG conversion kit comes with the following operative parts. It essentially is a build on system that retains all parts of the old fuel system and over it builds the new system to make it a duel fuel system capable of using Petrol / diesel and also LPG systems.

  • Tank, which contains the highly pressurised LPG in liquid form, comes in capacities of 30 to 100 ltrs. The tank which is an integral part of the whole conversion system must be fitted into the vehicle rear or boot space with metal straps in such a way that it must not shift while the vehicle is in motion. The tank has to be a permanent part of the vehicle. Some automobile manufacturers are now offering factory fitted LPG kits which are a much safer and more secure system.
  • The multivalves which controls and checks the filling of the tank comes with a 80% stop-fill safety feature. That’s means the valve closes not allowing further filling when 80% of the tank is filled.
  • A device which automatically shuts of the tank and the fuel supply in the event of a ruptured line. In older days when using LPG for automobile fuel was illegal in India some miscreants would use domestic LPG cylinders in their vehicles. Firstly domestic cylinders are not meant to be used in automobiles as a fuel option. Its design is not suitable for it, nor is its pressure valves which can control the flow of the gas in the event of an accident or rupture in the lines. In a proper LPG retor fitted system the pressure valves automatically controls the flow of the gas in the event of an accident thereby not allowing gas to be leaked inside the vehicle. This significantly reduces the possibility of a fire or explosion.
  • LPG solenoid valve controls the flow of LPG into the system depending upon the mode of selection.
  • Gasoline solenoid valve controls the flow of gasoline into the system depending upon the mode of selection.
  • Electronic control module which controls of the flow of LPG in fuel injection type systems
  • LPG / Petrol switch, which enables the driver to choose which fuel he wishes to use. This evidently means that your vehicle is able to use either source of fuel to run. So you are not limited to the supply of LPG when you are hitting the roads for a long drive.
  • Pressure regulator which enables the vaporization of the LPG from liquid to gas state.
  • Mixer / gas injection which flows the LPG into the combustion chamber
