Hello. I have been having this strange issue that I cant solve on my own. On my 1984 300TD the fuel hose that returns the fuel from injectors back to the system keeps rupturing at injector 1 (one closer to the front of the car). I keep replacing them, but after driving for a little bit, and especially at high speed it busts again and while my wife was driving behind me, she noticed a mist of diesel fuel on her windshield... Do I have a clogged return line or injector? I dont even know where to look... Also if it has anything to do with it, when its cold outside the car has a very hard time starting and runs sporadically untill it warms up.. (it did not used to do this). Thanks
