Anwen (Rockland, Massachusetts) - 81 Volvo 240
Anwen’s Volvo is makes a noise when the gas tank is half full, like the sound of chalk on a blackboard. She had the fuel pump checked and the mechanic said it was fine. Tom and Ray suspect that her mechanic didn’t realize this car has two fuel pumps and the one in the tank is the problem. It will probably need to be replaced.
