Hyundai Motor India — rat bite - fuel pipe

I am suryaa, a resident of bangalore, india. Twice in span of 4 months, my hyundai verna's fuel pipe has been chewed by rats and each time i have to spend 3k atleast. I notice this issues are more in hyundai cars and not in other brands. Why is this? Why dont you change the type of material used for these fuel pipe or come up with a new technology for this. I feel frustrated everytime when this happens. Luckily, my car hasnt catched up with fire when ignition is turned on.. Damn!!!
