Engine started pouring fuel out in large quantities coating the entire chassis. I was lucky, I had planned to go fishing early but had boat issue. Had I gone early in the dark it would have been catastrophic. Large amounts of gas. Pouring out. I'm lucky, when moving the truck my wife noticed the fuel was leaving a trail down the road and started screaming. I immediately parked the vehicle and I am waiting on support to get to dealer. The fuel system is a known defect on 2025/2026 silverado but not yet identified for this hd 2500 with same 6. 6l engine. Entire cab is full of gas fumes. This was extremely scary.
