Thread revival. Same thing happened to me this weekend. Parked nose down on the steepest part of my driveway. Gauge was showing right at 1/4 of a tank. Couldn't roll the truck forward because I was parked about a foot away from the tongue on my camper. Put a few gallons of gas in it and it cranked right up. Went to the gas station and filled it up and put 28 gallons in it. Lesson learned, I guess I'll be backing it in the driveway if I need to park there again. The worst part was I blocked my MIL in the driveway so she couldn't leave until I got the truck cranked.
