Recently I pulled into my driveway and noticed quite a bit of raw diesel leaking onto the ground under my truck around the front/passenger side area near back of engine. I looked around and couldn't pin point where it was coming from. I checked the fuel regulator area and it was bone dry. The next day it started up and drove fine and didn't do this again for quite a few weeks. My mechanic looked at it and said it was the fuel pump, and replaced it, but the fuel wasn't leaking around that location (drivers side under rear door?) A buddy of mine used the truck for the weekend while I was away and said it did the same thing for him one day, but I haven't seen it since. I'm talking a GOOD amount of fuel leaking.... Maybe 10oz. or so on the driveway. I had just finished a "spirited" backroad commute from work when it happened, and my buddy said he had the Bullydog on the extreme tune when it happened to him, so I would imagine he was raping her pretty good before it happened.... Any ideas?
