So I went and filled my truck up this morning and when I got home I noticed a steady drip of diesel fuel. So I have been underneath the truck looking for where it might be coming from, but I am not sure at all. I checked the cp3 pump and it is all dry. All the lines for the airdog are tight and are dry also. The only spot I can notice that is wet a little is the line that went to the fuel filter. I am not sure where else it could be coming from. Is it possible that I overfilled the truck and it leaked out there? Sorry not the best description and I don't have my camera with me or I would take a pic. The majority seemed to leak on top of the front diff so I am just stuck on where else it would be coming from?
thanks

 

Okay so after testing the truck a bunch of times it is definetely coming from the old fuel line that was connected to the fuel filter. The truck does not run rough or leak when it is idling. If you move the truck at all then it squirts out of that line a little. So I am guessing that there was some type of cap or plug on that line since it is not used at all? If so what does everyone use to plug it up? I am gonna try putting a bolt in it and see if that does anything.
thanks
