My vehicle failed to start upon leaving the mall. After several trouble shooting procedures at my resident the next day, I found that the in tank fuel sending unit was not working. During the gently lowering of the fuel tank, the sending unit to filter fuel line that runs along the inside of the vehicle frame just crumbled into chunks of rust. After further inspection, I can not believe that GM actually installed fuel lines made out of plain unprotected steel tubing, especially on a vehicle that was sold and operated in a snow belt state. Also while I was replacing the fuel supply and return lines, I noticed that the brake line that feeds the rear brakes that also runs along the inside of the frame was in the same sad shape, during removal of this brake line, it also crumbled into chunks of rust, how these lines did not fail prior to this incident is beyond me. If it wasn't for being a skilled mechanic by trade, this would have cost a fortune in labor cost to repair. For a vehicle sold/operated in snow belt states, these lines should have been made out of stainless steel or some other non-ferrous alloy material.
