Very fair point there SLO76 about the positioning of the second fuel tank and possible dangers.
On myMerc W124 it sits behind the existing fuel tank, which itself is an upright design full width just behind the steel rear firewall, and like the petrol tank across the boot, so probably as safe for people inside the Merc as the existing fuel tank, lose about half the boot (it is an 80 litre tank), but the car was never about luggage carrying nor a sole car.
The Outback's tank is a toroidal unit sitting in the spare wheel well.
The tanks are very strong, forget petrol tank minimal thickness or plastic even, and the extra tank doesn't worry me unduly, but i agree there are some cars where fitting an LPG tank would be unsatisfactory, and the conversion is not for everyone nor every car, if you worried about such things then it wouldn't be a good idea.
If anyone has statistics, anecdotes or any information about (properly fitted, not cable tied in by messrs bodgit and scarper) LPG tanks exploding in car accidents i would be interested to read.
