OK guys and gals, now I too have a fuel tank leak as of today. I was driving down the highway and noticed a diesel smell that would not go away. Was worried I had a high pressure leak under the hood, so I pulled over, left her running, and popped the hood. No fuel smell. I walked around the truck, and saw fuel spray on the rear windows. I looked under neath with her still running and saw substantial quantities of fuel dripping off the bottom of the tank. I was worried that I had thrown up some debris on the highway and holed the tank. I shut her off, and climbed underneath. (I still smell like diesel LOL) With the truck turned of the leak slowed and stopped. So no hole in the bottom. I had less than half a tank of fuel in her. I turned the ignition on, but did not start her back up. The fuel leak instantly returned dripping off the top of the tank and down the side.
What the heck do you think has broken, and how do you suggest I fix it?
She is a 2004 Freightliner 2500 with 298,000. miles
PS: She runs fine even with this leak. Turned around at the next exit and made it home and shut her off with no performance issues. She and I just stink of diesel. There is however a small puddle of diesel on my concrete driveway from before I shut her off.
