Noticed a couple of small recently deposited spots of liquid on the driveway under the fuel filler pipe area. Looked around and found a couple of older stains in the drive in the same pattern as the fresh ones. I reached underneath the truck and my hand came back wet with diesel fuel. I drove to the dealership and was told that a fuel Line check valve was bad and that I needed to bring the truck back on Tuesday so they can fix the valve and replace the fuel tank. Truck is a 2016 eco with 6800 miles. They said they needed to order the parts. Has anyone else experienced this?

No, but I found out if you over fill it, it will spill out of the fender in front of the wheel well housing!!!! OOPS!!

Turns out source of the leak was back pressure from the fuel tank. Dealership replaced the tank which seems to have fixed the problem. So far so good. Service tech said something about removing the fuel filler cap and placing it back on three times immediately after fill up. I am guessing that helps clear filler neck?
