I have a sweet 1983 Turbo 300D that will not start after a two year relationship. My daughter drives this car and it broke down on her while I was out of town. It is setting in a friend’s driveway until I have the opportunity to check it out. My neighbor, who owns an identical 1984 model, took a look at it and said that it sounds like it is not getting fuel. He replaced the fuel filter and noticed that a return fuel line was bulged. Could this be a symptom of the in-tank fuel screen being clogged?
