there is a sjhop opp japan plastic named Sabir rubber. beside sabir rubber a gali goes in, when u enter in that gali, on ur left there is a second shop which u can see having lots of pipes and some parts. i dont remember the shop name correctly but go there and you will find the best quality pipes both for fuel, brakes....metal and rubber both.
The guy has some stuttering problem while talking but he is a knowledgeable guy and can even provide the pipes exactly similar to the car make and model.
