years ago a young mechanic on the GT road near Wah decided it was a sheer waste to buy a specially designed CNG tank in the car. He installed the kit and then fitted an LPG cylinder to work as a storage tank. He made the proper fittings and drove to a CNG station with the owner of the car for the first fill-up.
We heard the boom about 10 miles away.
The medics had a hard time collecting the body parts of the young mechanic, the owner of the car and the poor CNG station attendant.
experimenting is good but some things are best not monkeyd around with... compressed flammable fuel gases being one
..just my 2 cents worth...
