What is this listing for?

This listing contains the correct under bonnet (front end) components to convert your pre 1999 Range Rover P38 engine to run successfully on LPG. Indeed with such a system your LPG conversion will not only half the price of running your car it will also have more performance and better economy too, the trick is in the upgrades that we supply with our systems to fully appropriate them for LPG use as well as enhancing petrol efficiency too.

Please note: all self fit LPG systems must be fully inspected to ensure they comply with the code of practise for LPG installations and registered on the UKLPG database. 

Switch Unit

Once fitted the LPG switch has two operating modes which are changed between by a simple push button.

  • Petrol: As the name suggests this mode is to run the engine on petrol and the LPG system is inactive.
  • LPG: This activates the LPG solenoids and allows the engine to run on LPG, with the petrol system inactive.
  • With this system you can select LPG only and no need to start up on petrol either.
Why a draw through kit?

Although many would tell you that a more expensive sequential injected kit is required this is not the case. We have converted hundreds of pre 1999 P38 Range Rovers using this Lambda Loop type of LPG conversion and there are no issues when converted and fitted properly. assuming that is you also adopt the upgrades offered and included here and your engine is in good shape.
