problem #2

Sierra 2500 8-cyl Diesel

  • 95,376 miles


Arriving at my rv site in Alabama from upper Michigan a neighbor saw something leaking from near the left front tire of my pickup. Upon determining it was diesel I immediately drove to the local Chevy dealer. They said due to the condition of the lines they all be replaced. Next day I was asked to come to the garage to look at the brake lines as they could not move any to get proper routing of the fuel lines.the lines attaching to the ABS modulator, total of 6, looked like you could crumble them with your hand so all were replaced as well. I pull a 33 foot fifth wheel and consider we were extremely fortunate nothing happened on the road.
