So i went to Costco today and when I came out and got near my truck I smelled diesel fuel. Looked on the ground and there was a big puddle and very active drip. I recently changed the filter so I assumed it was that, looked under the truck and it was nowhere near the filter housing. it was coming from somewhere up high near the back of the tank but before the fuel filler. I decided to get it home and look further. Get home, no leak. I can see the wetness of where it was coming from but did not dig to deep. Ran a few more errands, about 20 miles worth and still no leak. It was a very active leak with a steady drip and a big puddle. Truck was level, tank was 3/4 and filled about 5 days ago. I have a Titan tank but it was installed 50k miles ago and never had any issues like this. I don't want to drop the tank if I don't have to but I also don't want a fuel leak to pop up when I am on the road. It's the F250 6.7 PS in my sig. Anyone ever experience this?
