LPG Conversion basics.
Let's start off what goes in your trunk. Obviously we will discuss lpg propane tanks and your choices here.
There are many different types of lpg propane tanks you can choose from. All depends on what you think will work for you. Type of car you drive, amount of space available and placement will depend on which tank and size you will decide to choose.
When choosing tank size do not forget that propane tanks can only be filled to 80 percent of it's capacity. (This means that 100 litre tank will hold 80 litres of propane) - The tank will also be your most expansive part of entire propane conversion as they are heavy and shipping will be costly. If you can arrange for a local pick up that would be great. As for pricing, tanks will cost you anywhere from $60 and up to $1000.
