One problem related to other fuel system has been reported for the 2008 GMC Sierra. The most recently reported issues are listed below.
The fuel lines are rusted through spraying fuel to under side of truck. The lines rusted through while driving fifteen hours strait from florida. If the fuel would have hit the tail pipe or diesel particulet filter when regenerating, there could have been a serious fire. I have been through an explosion at work and know what it is like to be burned. I only drove this truck daily two winters before I got hurt and last winter it was in florida. I haven't even changed the front brakes yet but the fuel lines are shot. Shame on gm and shame on NHTSA for not addressing this. You both know there is a problem with brake and fuel lines. How many people need to die or get hurt or how many not even reported have been touched before you act. And by the way I have a mechanics degree from years ago but am not a practicing mechanic.
