no way man, its just ur fear , i have seen many severe collosions ,kabhie nahi howa k cylinder phut jaye ya agg lug jaye, aik accident may car hit hoyi front or back say, cng kit was broken in two pieces lakin koi agg nahi lagi, hit say cylider b nahi phutha, i think wid standard cylinder u dont have to fear this, and new fitting racks for cylinders r realy awsome,
