“While driving started to smell gas. On same day, car stalled at an intersection in a downtown area. I could not start car. Had to push car in busy traffic to a safe place and called a tow truck. Auto shop I took to said the fuel pump came loose somehow and caused the fuel lines to break causing the fuel leak. Had lines repaired. Fuel pump was not replaced and is working.”
